i have installed current clanlib from source on a debian 32 bit linux system on a notebook with intel graphics.

when i start the demos (e.g. pacman), the screen looks messed up, the pacman shows lot of blue dots and you can only slightly guess a maze. kinda like if rgba values would have been switched.

then after 1 or 2 seconds the whole system locks, no reaction at all, even killing x is not possible anymore, all i can do is switch off.

i can run other opengl or sdl programs without problem.

what could this be?
