--- Comment #14 from Roderick Colenbrander thunderbird2k@gmail.com 2009-11-05 10:50:47 --- I have come a little bit closer. Disabling the BitBlt in swapchain_gdi.c x11_copy_to_screen prevents the crash. I checked X11DRV_StretchBlt and each time it is called it also completes. Perhaps somehow it leaves something in a wrong state behind or so.
