From what I can tell, corruption happens when an icon is rendered off-screen. For \
example, when there are two rows of icons in a horizontal panel and the panel is \
resized such that half a row of icons is off the screen, that half of the icons will \
be corrupted after they are moved to their new positions. Having a resizable panel is \
probably what has shown this issue to show up so blatantly...

For the record, I tried setting BackingStore to Always on both the embed container \
window and the embedded window but without any luck.

I think that one way to solve this issue would be to reset the background pixmap of \
the client window whenever a paint is issued in the containing window, but I can't \
seem to figure out how to convert/rerender a pixmap from one depth to another. Any \
pointers on how to do that so I can give it a try?
