Picture of the problem
I had hit that one, too. But was never able to find a pattern to reproduce (sometimes it actually works). I can reproduce the bug consistently. Happens on every boot and has persisted over the last few days of nightly updates from project neon. ok, found the upper layer problem: QWindow::setMouseGrabEnabled(true) returns false, mouse and keyboard fail to grab. pushbuttons grab the mouse while down -> queued connection or explicit xcb_flush? (though that'd be really a problem if connecting "clicked" would break grabbing the pointer) (In reply to comment #5) > pushbuttons grab the mouse while down -> queued connection or explicit > xcb_flush? (though that'd be really a problem if connecting "clicked" would > break grabbing the pointer) wooha, your a genius :-) Yep that seems to be it, I already tested that updating Xtime makes the grab work again, but afterwards it break. No surprise the release... Qt::QueuedConnection should fix it and if that's the case I'm going to develop a test case for Qt. pity, Qt::QueuedConnection doesn't work. installing the grab on the kcm works, though. This is still a problem in nightly builds of project neon. Can't the preview just close whenever it loses focus? (In reply to enoopt.adams from comment #9) > Can't the preview just close whenever it loses focus? unfortunately not as it never gains focus. It's an unmanaged window.
