I re-tested WinUAE 1.5.2 with wine-1.5.16-59-gdf2c73a, Lubuntu 11.10, Nvidia
driver 304.51. This bug does seem to be fixed.

I also noticed similar messages to those in comment 5. While it might not be
directly relevant to this bug, some of them were:
err:d3d_shader:arbfp_enable >>>>>>>>>>>>>>>>> GL_INVALID_VALUE (0x501) from
glEnable(GL_FRAGMENT_PROGRAM_ARB) @ arb_program_shader.c / 5660
err:d3d_shader:arbfp_enable >>>>>>>>>>>>>>>>> GL_INVALID_VALUE (0x501) from
glDisable(GL_FRAGMENT_PROGRAM_ARB) @ arb_program_shader.c / 5665
err:d3d:context_apply_clear_state >>>>>>>>>>>>>>>>> GL_INVALID_VALUE (0x501)
from glReadBuffer @ context.c / 2178
err:d3d:context_bind_texture >>>>>>>>>>>>>>>>> GL_INVALID_VALUE (0x501) from
glBindTexture @ context.c / 1968

Changing to Direct3D filter sometimes results in no output (black emulation
window). But that would be a separate bug.

One time, after repeatedly changing graphics filter between none, null,
Direct3D and OpenGL, I did get a crash but couldn't reproduce it. Console
output then was this:
err:ntdll:RtlpWaitForCriticalSection section 0x7e85f968 "win.c:
surfaces_section" wait timed out in thread 0009, blocked by 0025, retrying (60
sec)
