Text appear corrupted in Iceaweasel (firefox), roxterm.. But xterm showing ok (perhaps some fonts are ok and other are not)
dual screen, dual head, both screens are samsung !sync!laster 206BW
Some pixels are also corrupted perhaps unrelated to text, e.g. in iceweasel/firefox tab titles.
Seems to be much better with latest git commits on xf86-video-nouveau: % git log commit 6dbf4ea12600275775123f9f564469454415da55 Author: Ben Skeggs <bskeggs@redhat.com> Date: Mon Jun 18 13:28:07 2012 +1000 bump version to 1.0.0 Signed-off-by: Ben Skeggs <bskeggs@redhat.com> commit 5e74cee90eeb4e8e638b371a5f1a2c6737be70ff Author: Ben Skeggs <bskeggs@redhat.com> Date: Mon Jun 18 15:36:47 2012 +1000 distcheck fixes
But the issue still appears sometimes...., probably much less frequently...
I'm seeing this as well on a GF116 [GeForce GTX 550 Ti] in single-head setup. (The card has two connectors, but I'm only using one). I've managed to grab screen dumps of the corruption and the corruption is present also in the screen grab. The corruption is typically resolved on a unfocus/focus on the window. Like the original submitter, I'm only seeing this in certain apps. gnome-terminal is heavily affected, emacs not at all, chromium to a very small degree (and then just in the location bar for me), hotot quite a bit. Happy to test any fixes you might have for this.
I also had this problem with a GeForce 8400 GS (dual head setup), using 3.5.0-rc3 and earlier kernel. It happens a lot in gvim, only with bold/italic fonts. Also in chrome tabs, and that's it. I just updated xf86-video-nouveau to 1.0.0 after finding this bug report, so let's see.
*** Bug 51645 has been marked as a duplicate of this bug. ***
I installed xserver-xorg-video-nouveau 1:1.0.1-1 from Debian Unstable and so far no more issues with pixel corruption.
I'm still occasionally seeing it with 1:1.0.1-1 for Debian.
It is remarkable that I haven't seen these artifacts in KDE/Qt, but only in GTK-based applications
(In reply to comment #12) > I'm still occasionally seeing it with 1:1.0.1-1 for Debian. Okay, I can confirm there are still issues. Now mostly menus that don't appear at all or incompletely until the mouse is moved over it to highlight items. Additionally, borders of floating windows do not appear (mouse-over tips in Eclipse in my case). Again GTK-apps only.

Again GTK-apps only. This sounds like what I see on PPC Nvidia FX5200 with the addition of half the screen being corrupt or black. An oversize image as desktop seems to replicate/exaggerate the problem. Increasing ydim of Virtual is one workaround that works for PPC nouveau users with this card. Moves corruption off screen? Not sure, but I thought it may be same as: https://bugs.freedesktop.org/show_bug.cgi?id=47266 References: http://ubuntuforums.org/showthread.php?t=1937940&page=2 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=668828
Does this still happen with the latest software (kernel, xf86-video-nouveau, xorg 1.14)
No response to re-test request in a month. Closing as invalid.
FWIW, I've not seen this in quite a while, so yeah, presumed fixed.
