Pic of corruption, second type, single pixel
I have exactly the same issue here. To me it appears that this issue only appears on the second display and it mostly takes some time until this issue appears. At least for me from the beginning all things are fine. I sometimes use KDE4 or XFCE using Ubuntu 8.10 and when using XFCE it appears within minutes whereas in KDE it take several hours of work until the corruption appears. All methods to get that corrupted mouse pointer captured failed and in framebuffer mode it doesn't seem to appear, so it is likely to be a problem in the driver. In addition to the corruptions that Alex mentioned I have an additional corruption with the mouse pointer itself. When I see that corruption the cursor can sometimes be corrected by moving the mouse into the first display and back again. I'm using a RV515 (ATI Radeon X1300) although the driver complains in the Xorg.0.log that DRI may not work correctly for R600 cards. (???) Created attachment 22182 [details]
behavior of "type 1" corruption
This is an exact reproduction of the "type 1" mouse pointer corruption as I can see it.

"type 1" and "type 2" areas on my dual-head
I managed to exectly find out at which positions the corruption areas are on my system. I created that image (2560x1024) because there may be some mathematical logic in there.

"type 3" corruption
I am experiencing this corruption in addition to the other two ones which always come together. This one seem to appear a bit later and it is not restricted to areas.
Sometimes it is only visible on the second display but after some time it also gets to the first display.
I've been hit by this too, but had reported it on the Ubuntu site: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-ati/+bug/320771 With help from there we've found that: - This only happens with the free driver (ATI's driver is fine) - It only happens with two monitors connected (one monitor is fine) - It only happens with the hardware cursor SWcursor=true removes the problem. It looks to me like the interference bands are 20 pixels wide, and repeated every 250 pixels across the screen, on both screens. Locations I've measured (very approximately) are: 1770 - 1989 2025 - 2045 2290 - 2299 2540 - 2559 It may also be worth knowing that this issue only occurs on my home computer, not at work, with the main differences between them being: Home: ATI 1950 Pro, 1x DVI monitor @1280x1024, 1x VGA monitor @1680x1050 Work: ATI 2600XT, 2x DVI monitors @1920x1200 Same issue here, I get flickering black and white lines when the cursor is in those approx. 20 pixel wide corruption bands on both screens, with the following setup: ATI Radeon Mobile X1400, Internal LCD @1680x1050, VGA monitor @1920x1200 Bug 13405 is a duplicate, only this time it's on the radeonhd driver. Something that might be relevant: The corruption appears to be visible when the cursor spans a strip that is the last 10 or so pixels of the stride value given here: http://cgit.freedesktop.org/xorg/driver/xf86-video-ati/tree/src/radeon_cursor.c#n204 i.e. pixels where x=245 to 255. This could be expressed as every (256*n-10) to (256*n) where n>=1. If you use a jumbo sized pointer you can see that the strips of cursor on either side of the range given are OK. There is an additional corruption which is seen as the cursor vertically bouncing. This occurs at 204+(256*n) where n>=0. I see both symptoms on both screens with an X1400 Lenovo Z61m using LVDS (1680x1050) and CRT (1280x1024). According to xdpyinfo these are treated as screen #0 @ 2960x1050 pixels. This was with 6.11.0.99+git20090305.5dc4b69f-0ubuntu0tormod~intrepid package. I'm currently also experiencing corruptions type 2 and 3 in an irregular basis across two screens using the proprietary fglrx driver (8.54.3) with a Radeon HD2400 PRO PCI-E. It is not really a problem because it appears and then it takes a few minutes and the corruption is gone completely. This is rather unusual and I didn't had such issues previously using Ubuntu 8.04 but now I did a fresh install of Kubuntu 8.10. In addition it indicates that this may not be a bug in the xrandr implementation as stated in some other bug as the fglrx 8.54.3 doesn't use xrandr. Machine data: - AMD Athlon 64 X2 4400+ Dual-Core @ 2.3 GHz - ATI Radeon HD 2400 PRO (RV610, PCI-E) - 2x 19" CRT @ 1280x1024@85Hz each Software stack: - Kubuntu Intrepid Ibex (8.10) - Kernel 2.6.27.11-generic x64_64 - X.org 7.4.2.0 - fglrx 8.54.3.2 (BigDesktop mode) - KDE 4.1.3 All drivers/software from the repos as I couldn't get the newer fglrx drivers to work with my two monitors. Xrandr implementations doesn't seem to be stable yet. In addition xrandr implementation in the drivers often use modes that are not appropriate for CRT's. Might this be a result of shared code between the proprietary driver and the free ones? I know that AMD already pushed a lot of code out to the world for free use and this code might be buggy. As these corruptions can be seen regardless of the Hardware actually used (or at least in a range of chips R5xx-R6xx) and regardless of the driver (+version) used. Can we also be sure that this involves only 64bit versions of the driver(s) used? I'm pretty sure the cursor issues are related to the watermark setup for the displays. Unfortunately, I haven't yet gotten any info on how to properly program them, but I got some new leads today. The open drivers do not share any code with the proprietary drivers. OK then, if driver code is completely separately developed but the same corruptions can be seen this bug is only partly related to the drivers then (as far as I suspect as I don't know the meaning of "watermark setup" exactly, as I'm just a lazy web developer). :-) Ancoron: I am seeing this on my Macbook 1,1 (Core Duo), so it's not specific to 64-bit. I'm running Ubuntu 9.04 beta (radeon 6.12.1, x.org, 1.6.0, kernal 2.6.28) with a radeon M56P (mobility X1600). I'm also seeing the corruption on both screens, apparently unlike some others. If I disable one screen, or set them to clone rather than left-of/right-of, it clears up, but when it's happening both outputs are affected. Two weeks ago I upgraded to KDE 4.2.0 from the Kubuntu testing repos plus a newer kernel and I've yet to see corruptions type 3. Also I have no input freezes anymore.
Kernel: 2.6.27-14-generic
X.org: 1.5.2
xserver-xorg-video-radeon: 6.9.0+git20081003.f9826a56-0ubuntu2.1
It is the same radeon driver version that ships with the stable Kubuntu repos and only the kernel and DM version changed. And some issues seem to be fixed for me.
@Kevin: What type of corruptions are you experiencing and when?
Well I must withdraw my previous statement. Today I got that type 3 corruption again after a week of a running system. System: RV635 Core2 Quad 6600 Debian testing. xserver-xorg-video-radeon 6.12.2 xserver-xorg 7.4. xrandr 1.3 kernel 2.6.29 with radeon drm module from git. Display 20" LCD (1680x1050) Problem: Change orientation via "xrandr -o left". All is ok until I press mouse button - cursor corrupt. It restored when I move mouse to some place, where cursor must change (to link in web-browser for example). When I enter some text I see artefacts on previos place of blinking cursor. If I enable SWcursor and enter command "xrandr -o left" - xserver fail and themself restarted. xserver-xorg-video-radeonhd 1.2.5 fail on command "xrandr -o left" - my computer is locked - keyboard doesn't response, but mouse work. This is my first bug report. Please ask me, if need more information. Thanks. Andrew, you will have to open a new bug report here: http://bugs.freedesktop.org/enter_bug.cgi I've fixed the "single pixel" corruption in e3c564114eea4d032f920fcebd4040f1934c21b0 The other one is watermark related and I should have a fix for that soon. *** Bug 16865 has been marked as a duplicate of this bug. *** Should be fixed now in git. Great Alex! I will attempt to build from Git and confirm the fix on my system. Any instructions for compiling from Git from a standard Ubuntu 9.04 driver? basic instructions here: http://www.botchco.com/agd5f/?page_id=2 When transitioning from screen to screen I'm experiencing left over cursor images on the screen I transitioned from. My cursor is still functional on the active screen, however, and the image goes away once I return to the other screen. The behavior was first introduced in commit: http://cgit.freedesktop.org/xorg/driver/xf86-video-ati/commit/?id=4e948e2aaa59267a9aa797396add2c6b7b4c1e7c (In reply to comment #24) > When transitioning from screen to screen I'm experiencing left over cursor > images on the screen I transitioned from.

I saw the behavior Brian described briefly but I believe the reason was I hadn't done a full restart after installing, only an X restart Great job! I installed Tormod Volden's -ati/-radeon packages for Ubuntu that I believe should have these fixes. When I restart the computer after stand-by the cursor flickering comes back. The flickering disappears (for good in that session it seems) when I click once on the second screen in my laptop setup. I'm running ubuntu 9.04 on a laptop with a Radeon Mobility X1600 gfx board. Thanks! -Arto Just to add to the chorus of approval, I'm also on the Tormod Volden packages for Ubuntu, and it is totally fixed for me too. Many thanks (I know this was minor, but it really used to irritate me!) i compiled 35183ef528411eb0122cf48550d93f921d291d12 a week ago and it works fine till now. thanks alex! --- ubuntu 9.04 radeon VGA compatible controller: ATI Technologies Inc RV516 [Radeon X1300/X1550 Series] Yepp, tested on a HD2400Pro and an X1950XTX and finally the cursor got fixed. Thanks Alex! Sorry for the reopen but today the problem reappeared (similar to type 2 corruption, but not thinner at the top and not wider at bottom). This appeared on a system with an X1950XTX using GIT master up to commit 2b9a5be3bb22fad1d52ec9eea7733c5e956250b7. The system was running for about a whole day (no system standby or suspend in between, just monitor blank/off via DPMS). Regards, Ancoron Well, I have to add something here.
Shortly after the corruption appeared (around an hour or so) the cursor changed into a square as I moved the cursor from one screen to the other. Additionally the cursor moved with a delay and not smooth at all. After that the keyboard was inaccessible and logging in via SSH remotely (which took quite some time) I saw that Xorg was using almost all CPU (dual-core AMD X2) and what I was curious about was that even 'top' was using very much CPU (~20-60%).
The system didn't come down correctly after issuing a 'shutdown now' so I had to hard-reset the system.
Although the mouse pointer was movable (hardware cursor) the system didn't respond to anything.
My current setup:
xorg: 7.4~5ubuntu18
xserver-xorg: 7.4~5ubuntu18
xserver-xorg-core: 1.6.3+git20090801+server-1.6-branch.f274e595-0ubuntu0sarvatt~jaunty

That's a GPU lock-up. (In reply to comment #33) > > That's a GPU lock-up. > OK, that's why I asked about the ability to monitor temperatures a while back on the mailing list. The system runs fine now till then, although I experienced the mouse cursor corruption from time to time but it disappeared after some minutes when I move the mouse from one monitor to the other. Is it possible that the corruption itself is caused by high temperatures of the GPU? Seems unlikely to me but I'm not a GPU expert. This has reappeared for me. I had not seen it for a long time, but after recent upgrade to Fedora 14 it has reappeared. It is does not always seem to be present, and may be related to suspend/resume. That is I think it only happens sometimes after the system resumes from a suspended state. Created attachment 41465 [details]
Xorg.0.log when corruption present
I have type 3 and Single Pixel (vertical and vertical + horizontal .. ill say 128x128 px area) type corruptions when playing Heroes of Newerth. There is no way to reproduce it easily, but its quite often issue. It happens when you scroll the map on edge of the screen (for some reason i think it happens only at corners). GPU is AMD Sumo on 3870K APU. It happens for quite longer time. Im using Linux 3.11 with DPM enabled (but that does not matter as it happened on older kernels as well) and git mesa from ubuntu PPA. Feel free to ask for more informations. Fixed as per https://bugs.freedesktop.org/show_bug.cgi?id=19215#c26 . |

This only affect the cursor and does not effect the windows. there appears to be two types of corruption, thicker and thinner. thinner might only be 1 pixel and the thicker could be say 10-15 pixels. I have seen this in both the stock Ubuntu 8.10 xserver-xorg-video-radeon driver and a newer git build (20081129). First bug report, so please do ask for more information.
