[[!img media/om.jpg alt="today i had the already mentioned problem: **xbuffer screwup**" style="float: right"]]

i played with the openmoko to get an idea what could cause this and i come up with this:
	
  * system widgets are not affected much but they are.
  * tangogps draws the map on the screen afterwards it draws an overlay over the map:
this overlay is used to draw the track with red color, you probably have used this already
the funny thing is that on a move event of the map the second layer isn't drawn and does NOT contain screwed images. after i release the screen the overlay is drawn and the map is filled with black random pixels and some other colors as well.
  * later i restarted tangogps and then all the pixmaps were screwed no matter if i used the map move or not

**openmoko using shr # dmesg**
