--- Comment #6 from Jörg Höhle hoehle@users.sourceforge.net 2009-10-21 03:27:43 --- I put glDisable in ~0.9.32 commit 7126b636 into Impl_Clear right before LeaveGL(). No improvement. (Is that the correct place?)
So if I understand you right, what's needed now is
porting the clear tests from dlls/d3d9/tests/visual.c to dlls/d3d8
and see if results differ from d3d9 on MS-Windows?
