Comment 1 for bug 862455

What version of Ubuntu is this happening on? And what hardware and graphics driver/s? If it is ocurring with the radeon driver it might be solved by this upstream commit to xf86-video-ati

radeon: avoid segfault when pixmap exceed GPU capabilities

We might get a request for a pixmap/drawable that is too big
for GPU capabilities in the dri2 get buffer path. In face of
such things just return NULL to dri2 get buffer request. The
GL driver should then use something like transparent black to
avoid something too ugly on the screen.
