This is interesting. I've occasionally seen my engine just display a mess of triangles, but if I was to kill it and start it again, it would work fine. This only happened very occasionally so I could never track down the problem. If running more than 13 glxgears shows the problem then maybe it would have a chance of getting fixed. :) You might want to open a bug report on the Freedesktop Bugzilla. The lockups are nothing new, unfortionally. I think there is a bug somewhere in the R300 driver. You can also get deadlocks which are a little different... I think that these might go away after R300 uses TTM and thus doesn't grab the hardware lock anymore for texture upload, etc. ------------------------------------------------------------------------- This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.
