Just so happens I have an MSI 5450 in my workstation (long story short the ball bearings in my Bonaire gave out and I wanted something quiet for text editing...). I'm using the latest upstream UMD and KMD from Fedora 24 without issue since day 1. This is very likely a distro issue. OK. Let's try to find out if it's a distro, XFCE, or xscreensaver issue. Are you also using XFCE and xscreensaver ? Tom, let's not jump to conclusions. Markus, please attach the corresponding Xorg log file. (In reply to Markus Näher from comment #0) > The issue occurs since one of the latest software updates, [...] Which packages were updated as part of that? Markus, did you see comment 3? The information I asked for there is important for making progress on this report. The packages that have been upgdaded at the moment when the issue occurred irst are hard to say, since it's been a few months since then. The reason why I reported the bug so late was that I first tried to get help from the XFCE folks but then they said it looks like a driver issue. Second reason is that I used the borrowed Radeon HD 7750 on the more important PC for quite a while, hoping that the bug would be found and fixed before I need to give it back. I'm attaching my Xorg.log, but it show only the massages from startup. I've just double-checked that there is no log when the issue occurs: I rebooted the PC two days ago, and on the day after reboot, the isue occcurred the first time. After that, the file content and date were still the same as after reboot. I'm trying to create some screenshots. But when I hit the "print" key (associated with xfce4-screenshooter), it immediately redraws parts of the screen and the redrawed screen is then saved as screenshot, and after that it flickers back to the corrupted display.

Xorg.0.log
FWIW Fedora 24 stable has X 1.18.3 and xf86-ati-driver 7.6.99 according to the log. So could very well be something new in the X or radeon usermode driver. Markus, is there any chance you can try if the problem also occurs with current upstream xf86-video-ati Git master, or alternatively with the xf86-video-ati 7.6.0 release? Does turning on/off the XFCE compositor avoid the problem? If so, are there any specific XFCE compositor settings with an effect on the problem? Michael, yes, it looks like there is a package named xf86-video-ati-git for my distribution. It's currently flagged "out of date", but I can try and check what exactly is out of date and then test it. Before that, I would like to set up a backup system on a second partition, just in case I screw up something. Could take a few days ... Tomorrow, I can test if turning off compositing makes a difference. Today, I managed to create a screenshot that shows the effect very well. I blurred some parts for privacy :-) I'm attaching two screenshots: one when the screen was corrupted and a second one shows how it should have looked like in that moment. This time I was lucky and could "fix" it by switching back and forth between virtual desktops in order to redraw the whole screen. After this, everything worked for an hour or so. There is one more interesting thing: When creating a screenshot, the current screen content becomes the new "saved state" that always is displayed when the issue occurs. On top of that, a varying number of window fragments are drawn. E.g. the CPU usage graph, sometimes the clock etc ... BTW ... when the screen is corrupted, x11vnc also shows the corrupted content. No, x11vnc is not running all the time, and the issue also occurs when x11vnc is stopped. :-) Created attachment 126309 [details]

Something else you could try is whether Option "AccelMethod" "glamor" in /etc/X11/xorg.conf has any effect on the problem. How do I set it in xorg.conf.d ? I just checked the docs at https://www.x.org/archive/current/doc/man/man5/xorg.conf.5.xhtml, but could not find anything about it. Disabling compositing seems to help. No occurrences so far today. (In reply to Markus Näher from comment #13) > How do I set it in xorg.conf.d ? You don't. :) xorg.conf.d is for system configuration snippets, users should always use /etc/X11/xorg.conf directly. Something like this should do: Section "Device" Identifier "default" Driver "radeon" Option "AccelMethod" "glamor" EndSection > Disabling compositing seems to help. No occurrences so far today. Can you attach screenshots of all XFCE settings tabs containing any compositing related settings? Well ... I asked about xorg.conf.d because there is no xorg.conf on my PC's. As far as I understand, this means my X server is autoconfigured except a few things in my xorg.conf.d. Currenntly, it's only keyboard settings and dual screen positions (DVI-1 right of DVI-0). I'm trying your proposed settings as soon as my current long running job is done. It runs in a GUI app, so I can't even restart X. About the radeon-git package ... as I said, it is flagged as outdated, but I found out it's even worse ... the maintainer abandoned it. So I'm afraid I won't be able to install the git version. But I have another idea: I was lucky to find a cheap used Radeon HD 7750 with passive cooling, so one of my two PC's does not have the problem anymore, and one of the 5450's is now left over. As your name looks like it could be german (and hopefully you live in europe), I could send you the left 5450 via mail. This could be easier (for both of us) than you advising me how to test and possibly debug. If that's OK for you, you can contact me via the EMail link on my name and give me your postal address. I promise not to bother you :-) Another interesting thing; When I re-enabled the compositor for making the screenshot of the settings, the issue showed up immediately.

(In reply to Markus Näher from comment #15) > Well ... I asked about xorg.conf.d because there is no xorg.conf on my PC's. > As far as I understand, this means my X server is autoconfigured [...] Yep, that doesn't change what I said. :) > As your name looks like it could be german (and hopefully you live in > europe), I could send you the left 5450 via mail. > This could be easier (for both of us) than you advising me how to test and > possibly debug. My last name is German (though I'm Swiss), but I'm currently living outside of Europe. Anyway, I do have a 5xxx card, the problem is "just" finding the time to try and reproduce and fix the problem; I'm afraid it's not very high priority for me. Anyway, since the problem doesn't happen with a 7750, it's quite possible that using glamor will avoid it with a 5450 as well. Today, I activated glamor and re-enabled compositing. Additionally, I did my routinely system upgrades, and one of the upgraded packages was xf86-video-ati from 1:7.7.0-1 to 1:7.7.1-1. Testing is in progress, and looks good so far. End of next week, I will report again if it's really totally gone. I would like to test a whole week because I always had the impression that it's getting worse with growing uptime. It did not happen any more with glamor. Thank you for your help. (In reply to Markus Näher from comment #19) > It did not happen any more with glamor. Does it still happen with EXA with 7.7.1? Yes, it does. Occurred 1 minute ago. Sorry for the delay, but I try to reboot (or restat X) as rarely as possible. There is one more thing I'd like to ask ... Would it improve performance if I configure glamor for the PC running with the Radeon HD 7750 also ? And even more important: I have set up a multimedia PC for my parents with an on-board Radeon HD 4200. It has sometimes performance problems playing HD-video. Would glamor help there ? (In reply to Markus Näher from comment #22) > There is one more thing I'd like to ask ... > > Would it improve performance if I configure glamor for the PC running with > the Radeon HD 7750 also ? SI and newer only support glamor. So that is the only option. > > And even more important: I have set up a multimedia PC for my parents with > an on-board Radeon HD 4200.

More important would be to make sure vdpau is enabled properly for hw accelerated video decoding and that the app you are using for playback is properly configured. -- GitLab Migration Automatic Message -- This bug has been migrated to freedesktop.org's GitLab instance and has been closed from further activity.
