the python program that causes the crash

I tested it with amanith-0.3 and PyAmanith-0.3.34

Comment 4 Giorgos Giagas 2008-06-30 09:54:08 UTC

in the python program, if I remove the strokegradient or make the path sorter it doesn't crash.

Comment 5 Wang Zhenyu 2008-06-30 22:01:44 UTC

Could you try with "export LIBGL_ALWAYS_INDIRECT=1"? Seems like a dri GL driver bug.

Comment 6 Giorgos Giagas 2008-07-01 01:13:40 UTC

With LIBGL_ALWAYS_INDIRECT=1 it doesn't crash.
A wine app that was crashing also works with it.
On closing the wine app though I encountered a different crash. Should I investigate this also?

Comment 7 Wang Zhenyu 2008-07-01 01:25:30 UTC

Not here please, they may trigger different problems, feel free to open new bug.

reassign to haihao as this is a dri driver issue.

Comment 9 Giorgos Giagas 2008-07-01 04:03:57 UTC

I don't want to make this report about any of these other problems but with LIBGL_ALWAYS_INDIRECT=1 the rendering is different than what it should be. Also if I enable compositing in metacity it crashes even with it (Propably also a different crash)

Comment 10 haihao 2008-07-17 23:49:53 UTC

fixed in mesa_7_0_branch. (5ce5cc93d51bc784a54aa4f51298715fa2c8d5aa)
