Hi list !
If a post something that have been reported many times, Im sorry. But I searched to google and to this ML's archive and didn't find anything close to what I got.
Ive coded a little game (ensemblist, hosted at savannah), and I just realized that the game does not work on my new laptop (dell d600, with a radeon 9000 vide card).
Ive spent my week end to get a simple code that reveal the bug, and there it is n attachment.
Symptom : after several call to the display function (about 30), the computer start freezing (strace last words : mmaping something).
The incredible thing here is how the bug is related to the alpha channel : in the exemple below, if I change the glColor4f by a glColor3f or, more incredibly by a glcolor4f(r,g,b, 1.), then there is no freeze anymore. I hope this rings a bell.
Here is the code (wich display nothing, but quit without freezing on all computers I tested it on, except the dell with the radeon card. If you want to know if DRI is installed OK on the dell : yes, and quake 3 runs incredibly smooth :-)
I've compiled and run it; it didn't crash (aborted it after the 1000th call) (with a radeon 9000pro).
What XFree86/DRI version are you using?
