Tested on system with CLE266 chipset. Applications that can draw on whole 
screen, eg. web browser, cannot be rendered properly. Resulting picture is 
different, but mostly white areas instead of widgets and window decorations. 
However widgets will be redrawn properly on mouse over event.  Please note 
that this is for full screen applications on big resolution and 24bbp. If 
same application is resized to use approximately 800x600 it is rendered 
properly. Some times I noticed that area of (lets call it main screen) about 
1024x768 (aligned top-left) is duplicated on right and bottom sides of whole 


When I start same system with resolution 1280x1024 at 16bbp - everything 
renders properly. It looks like some memory management problem in the driver.
(ver. 0.2.1)
