--- Comment #29 from Starks erappleman@gmail.com 2010-06-18 03:28:38 --- I'm still seeing this bug on my machine.
Intel i945gm Mesa 7.8.1 Xserver 1.8.2 Linux 2.6.35 rc3 Wine 1.2 rc3
Touhou 11 and 12 are pretty much unplayable. 10 fps in fbo mode. 30 fps in-game (60 fps menu) in backbuffer and pbuffer modes.
Touhou 10 has it's problem spots during complex scenes, but works fine. All of the older games are fine 90% of the time.
