           Summary: KDE's Kubrick has problems with xf86-video-nouveau
                    driver
           Product: Mesa
           Version: git
          Platform: Other
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/DRI/nouveau
        AssignedTo: nouveau-PD4FTy7X32lNgt0PjOBp9y5qC8QIuHrW@public.gmane.org
        ReportedBy: johannesobermayr-Mmb7MZpHnFY@public.gmane.org


I only post what I communicated with Ian Wadham (Kubrick developer) and KDE
games devel:

openSuSE factory and additional packages from
http://download.opensuse.org/repositories/home:/oertel:/Radeon_DRI2/openSUSE_Factory/:
 - Mesa 7.6 devel (20090807), drm modules (20090812) and libdrm (20090807)
 - Geforce 2 GTS (NV 15)
 - crash on start (see backtrace)
 - It works with my ION system and Mesa 7.6 devel...

Comment from Ian:
Kubrick has just loaded a background from a 2-D SVG file, rendered it to the
size available in the window and painted it in the bottom left of a QImage
that is 1024x1024 pixels, which is then "bound" into an OpenGL texture,
using QGLWidget::bindTexture (QImage &).  And after that it crashes in
the libraries or drivers somewhere (items #5 to #21 in backtrace [1]). AFAIK
it is valid to bind a texture during the initialize phase of OpenGL, because
you are just cacheing the texture and getting its handle in the return value.
You are not drawing anything.
