Can't confirm, works for me. Could that be related to the desktop environment?
I'm on latest KDE plasma, alt-tab doesn't change a thing.

If it only appears sometimes, can you try to run the tests from my two patches
to see whether the WM_PAINT messages arrive? There really shouldn't be
randomness involved.
