Created attachment 604075 [details] screenshot of gdm login page This is an old x86 (32-bit) computer with on-board Geforce4 MX [10de:01f0] updated to current F17. It previously had F15, but that didn't work for a different reason (bug 598767). 2D graphics appear to be OK now, but anything involving GLX in a large enough window is so corrupted as to be almost unusable. This includes the gdm login screen (but kdm is OK). The main features of the corruption involve (a) alternate pixel lines being blank, and (b) 16-pixel-wide columns being mixed up. The blank pixel lines are black in the screenshots I'm about to attach, but they can often also be white and will occasionally contain copies of irrelevant graphics that were previously on the screen. If I log in under GNOME, my whole desktop is corrupted. If I manage to start a terminal and type "killall gnome-shell" the corruption disappears. If I then start glxgears, the corruption is visible only inside the glxgears window - this also applies to a couple of other random GL demos I tested. If the glxgears window has a width of 320 pixels or less, it displays fine; if it's enlarged to 321 pixels, it's corrupted. This also appears to be true of the other demos I tested, although in the case of atlantis (from xscreensaver), the magic number is 192 instead of 320. In addition, there is no restriction on height of the window. Version-Release number of selected component (if applicable): kernel-PAE-3.5.1-1.fc17.i686 xorg-x11-drv-nouveau-0.0.16-37.20120306gitf5d1cd2.fc17.i686

This message is a reminder that Fedora 17 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 17. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '17'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 17's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 17 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior to Fedora 17's end of life. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
Fedora 17 changed to end-of-life (EOL) status on 2013-07-30. Fedora 17 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. Thank you for reporting this bug and we are sorry it could not be fixed.
Exactly same behaviour under Fedora 19. kernel-PAE-3.10.3-300.fc19.i686 xorg-x11-server-Xorg-1.14.2-7.fc19.i686 xorg-x11-drv-nouveau-1.0.7-1.fc19.i686 GNOME only survives for a minute or so before saying something went wrong and inviting me to log out. The magic numbers mentioned above are different: 448 for glxgears and 320 for atlantis. However, I'm probably decommissioning this hardware soon.
