I can reproduce this problem in at least Return to= =20 Castle Wolfenstein (version 1.1b) and Tux Racer. I am using a 32 MB ATI Rage Pro 128 on Debian woody (XFree86 4.1). If I run= =20 Tuxracer or RTCW, and wait for the game to load, everything is alright.=20 However if I switch to a spare virtual terminal, and switch back to X, the= =20 fonts become illegible -- they just appear as coloured boxes with no=20 outlines, making things unplayable. The problem does not occur when using software based OpenGL rendering which= is=20 why I believe DRI/DRM is involved. This problem only occurs when framebuffe= r=20 is enabled in the kernel, if framebuffer is disabled the problem disappears= ,=20 so I believe framebuffer is also at fault. Greatful for any help...
