After upgrading from karmic to lucid I began to experience a strange problem. After booting everything is fine for some time. Then at unpredictable moment graphics goes weird. Resolution and refresh rate did not change. No such problems when using windows xp (so it should not be the hardware itself). After rebooting graphics is again ok for some time.
Here is the video of what's going on:
