--- Comment #6 from Brian Paul <bri...@vmware.com> --- (In reply to comment #5) > Created attachment 75068 [details] [review] > another attempt to fix pbuffer initialization > > Hmm is it legal to use XGetGeometry() with pbuffers? Not normally, but in the glx/xlib code we create a dummy pixmap for each pbuffer so that we have an XID that we can pass around. > I think something like this patch would be better. That would be fine too. It's what I first tried. > Not sure if guarding against zero-sized buffers in drivers is needed.

Softpipe worked but the llvmpipe assertion failed. I guess I'd consider the llvmpipe change to be a defensive coding check. One less way for llvmpipe to fail is good thing. -- You are receiving this mail because: You are the assignee for the bug.
