      Not all test functions that use Qt::X11BypassWindowManagerHint exhibit this behavior, but many do (the above list does not attempt to list them all). And most of those test functions are also marked as blacklisted, as they cause qWait*s to fail (expire?).

      Verified on 2 distributions (Ubuntu and KDE Neon), both exhibit this issue.
