Public bug reported: Binary package hint: xserver-xorg-video-intel
On karmic with an i945: OpenGL applications and games stutter in a strange way. I'll see a few frames at full motion, and then a very short pause. A few more full frames, then another pause. Repeat. This happens two to three times a second. However, none of these applications notice any framerate drops. Glxgears reports it is blitting at 4500 frames every 5 seconds, but taking into account the stuttering there is likely a lot less actually being displayed. Nexuiz is claiming a solid 30 to 40 FPS, though it also exhibits this strange behavior. Compositors do not appear to be affected. I have no issue with the 2.6.30 kernel series from earlier Karmic packages. Everything runs at full speed without any issue. (To that point, I'm not sure if this should be reported against the kernel. Or mesa.) This issue persists: - with and without compositing - with and without KMS - with and without forced vsync in driconf This *might* be related to bug 416073, however the issues described there are about lower framerates overall, so I'm doubtful this is a duplicate.
