The first issue has been resolved. Because I have a bad modification in qxl dirver. Spicec don't core dumped after when I change the qxl dirver to original. But the preformance isn't better than using sw canvas.
Can you give me some precious suggestion if i want to improve the gl canvas performance. Thank you!

The 2d canvas code isn't probably fitting the gpu very well. (too much upload/read of textures, not enough batching, old gl code lacking optimization etc.)
