i am using msi wind u100 + ubuntu 9.04 and this bug appeared after i DIS(!)connected a connected external monitor from the dsub of the laptop. internal display is 1024x600, external was 1024x768 on a 2048x~1158 monitor. while connected netbook-launcher was fine. after disconnecting the bug appeared. it starts when i mouseover any icon on the desktop or clicking on go home applet to reveal the desktop, the graphical "animation" is extremely slow (about 8 seconds for recoloring appname to orange and enlarging icon) and cpu goes to 50% (hyperthread atom). when i alttab to an application and hide the desktop cpu load goes down in about 4 seconds.

i have this in syslog every 2 seconds _*WHEN*_ THE cpu is under LOAD:
kernel: [ 2153.331349] [drm:drm_wait_vblank] *ERROR* failed to acquire vblank counter, -22
