GNOME Bugzilla – Bug 711261
Black window in cube example
Last modified: 2013-11-28 12:39:23 UTC
Created attachment 258740 [details] Output of glxinfo When running tests/examples/generic/cube/cube, the window that is created remains black. FPS information is printed regularly (remains at 60 FPS unless I set the vblank_mode environment variable to 0, then I get around 1500-1600 fps). This is with git gstreamer/gst-plugins-* updated today. Attaching the output of glxinfo.
Same here, just 75fps instead
Works fine here. We use EGL by default but even so the glxinfo is still useful Can you try running it with MESA_DEBUG environment variable set? [1] If that turns up anything, can you break on _mesa_error() in a debugger and provide a backtrace of all the threads? [1] http://www.mesa3d.org/envvars.html
I don't get any more information when running the example with MESA_DEBUG=1
Ok, I did not realise before re reading your comment that this is using EGL. I think my EGL driver (intel mesa, as provided in ubuntu 13.04) is faulty. The example runs nicely if I set the EGL_DRIVER environment variable to egl_gallium or egl_glx (and is broken with egl_dri2, which I assume is the default). Sorry for the noise.Thanks for taking the time to report this bug. However, this application does not track its bugs in the GNOME Bugzilla. We kindly ask you to report the bug to the application authors. For a selective list of other bug tracking systems please consult http://live.gnome.org/Bugsquad/TriageGuide/NonGnome. If the affected third party application has a bug tracking system you should investigate whether a bug for the reported issue is already filed in this system. If it has not been filed yet please do so. Also ensure that both bug reports contain a link to each other. Thanks in advance!
