           Summary: [NVA8] UT2003: Splash-screen is transparent with
                    gnome-shell enabled
           Product: Mesa
           Version: unspecified
          Platform: Other
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/DRI/nouveau
        AssignedTo: nouveau at lists.freedesktop.org

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

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.

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

I tried obtaining an APItrace from ut2003, but likely this fails because it
uses its own GL wrapper library. As a result, ut2003 segfaults.

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.
