--- Comment #63 from Ove Kaaven ovek@arcticnet.no 2009-06-20 22:00:23 --- A workaround for now seems to be to simply disable render_texture_emulation. Unfortunately it doesn't seem anybody made a configure option for that yet. You have to edit dlls/winex11.drv/opengl.c and change static int use_render_texture_emulation = 1; from 1 to 0.
