Created attachment 47340 [details] Screenshot of the transparent splash-screen When Gnome-Shell is enabled and I try to start Unreal Tournament 2003, the splash screen is not shown with a black background. Instead, there is a high level of transparency, which can be seen in the attached image. If I change the gnome-shell background to black, the image shows correctly. This implies that there is no missing colour information but instead an incorrect alpha value is used. With gnome-shell disabled the splash screen shows as normal. Dmesg or console output does not show anything strange. Running: kernel-2.6.38.6-27.fc15.x86_64 (but also tried with Koji kernel and upstream nouveau module) mesa-dri-drivers-7.11-0.11.20110525.0.fc15.i686 xorg-x11-drv-nouveau-0.0.16-24.20110324git8378443.fc15.x86_64 xorg-x11-server-Xorg-1.10.1-14.fc15.x86_64
Bug exists with the following software: kernel-3.3.0-4.fc16.x86_64 mesa-dri-drivers-7.11.2-3.fc16.x86_64/.i686 xorg-x11-server-Xorg-1.11.4-2.fc16.x86_64 DDX from GIT April 2nd 2012
Could you retest this with a more recent mesa (e.g. 9.1.6 or 9.2-git)? [And the other stuff could stand an upgrade as well...] In case that the problem persists, try to capture an apitrace, and see if the problem still happens when you replay that apitrace (https://github.com/apitrace/apitrace, although there are probably also distro packages for it). If the problem happens with the apitrace, compress/upload it to this bug.

[And > the other stuff could stand an upgrade as well...] Retested this issue with mesa-libGL-9.2-0.14.20130723.fc19.[i686|x86_64] kernel-3.11.0-1.nouveau_git.fc19.x86_64 (rc3 I think) xorg-x11-server-Xorg-1.14.2-9.fc19.x86_64 xorg-x11-drv-nouveau-1.0.9-1.fc19.x86_64 > In case that the problem persists, try to capture an apitrace, and see if > the problem still happens when you replay that apitrace > (https://github.com/apitrace/apitrace, although there are probably also > distro packages for it).

As a result, ut2003 segfaults.
Created attachment 109783 [details] xtrace from ut2003 splash screen - nouveau following imirkins suggestions I got an xtrace of this problem, as attached. Also: this problem exists not only with nouveau, but also shows on i965 (4th gen). I assume this means the bug is more general than nouveau and should move up the hierarchy.
