I recompiled OCC and pythonOcc, but still the exact same issue. It really seems to be a bug with intel driver new functionalities (DRI2/UXA). Unfortunately I don't knw much about those new stuff. I found a bug report with apparently the same backtrace (from level 0 to 3). They say they solved it in May. But I think it is the same bug here. I will try to have the bug thread open back. Loïc
