Description
The bug is reproducible on Merlin build 1.4.0beta-b20 on all Win32 platforms.

Set your color resolution to 16bit, start demo/applets/DitherTest
demo. When it's up change color resolution to 8 bit. Note colors change
on the DitherTest's frame. Activate DitherTest's frame (click or resize it) 
garbage will be painted outside of the frame on the screen.
Resize the frame again and it will repaint correctly.
