--- Comment #10 from Tobias Jakobi liquid.acid@gmx.net 2008-10-17 16:59:46 --- Bisection verification:
Reverting the commit on top of current git master produces the same behaviour like the patch by Henri.
Checking out the tree with latest commit d37c6fc0a94b3ac3b4cce58afeafbdf225107b80 produces: Issue there!
Reverting the commit on top of that: Issue gone!
So something happens between d37c6fc0a94b3ac3b4cce58afeafbdf225107b80 and git master tip that changes behaviour of the code in such a way, that reverting the commit does not fix the problem.
Next thing: Check isInDraw flag and the GL error, that is produced.
