Comment 6 for bug 630632

Based on your previous comment, I'd guess that this is now fixed in Maverick.

The lack of mouse input is going to be a separate issue. If the windows are being repainted - and given that you can resize them, it seems that they are - then mesa's job is finished :).

Please feel free to file another bug about the mouse input issue - particularly if you can find a way to make it happen regularly.
