Applies to 8.0.x and 9.0. It's worked around for now ("Check that pixmaps which aren't managed by us actually exist before binding") but a proper fix should be added to mesa. some stacktraces: https://launchpadlibrarian.net/115551011/Stacktrace.txt https://launchpadlibrarian.net/115545323/Stacktrace.txt https://launchpadlibrarian.net/115549285/Stacktrace.txt https://launchpadlibrarian.net/115587684/Stacktrace.txt https://launchpadlibrarian.net/115563588/Stacktrace.txt https://launchpadlibrarian.net/115553644/Stacktrace.txt Reply at: https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/927168/comments/29 ------------------------------------------------------------------------ On 2014-11-24T20:56:50+00:00 Jfonseca-e wrote: IIUC the compiz-core patch https://i116412274.restricted.launchpadlibrarian.net/116412274/2c4b2354 -00dc-11e2-a4a9-002481e91f22.txt?token=60HdnFNMGFc5zJXJwfwH9pN2wg6pmXxn the fix consisted of not calling glXBindTexImageEXT when XGetGeometry (dpy, pixmap, ...) returns false. https://www.opengl.org/registry/specs/EXT/texture_from_pixmap.txt does say that "Currently, only pixmaps can be bound to textures. If <draw> is not a valid GLXPixmap, then a GLXBadPixmap error is generated." so indeed this should be handled better. This technically is a bug in st/dri though.
