[kwin] [Bug 383052] KDE allows applications to freeze whole GUI
https://bugs.kde.org/show_bug.cgi?id=383052 --- Comment #8 from Alain Knaff --- >> I'm just wondering why such disruptive functions still exist in the X API :-( > > Because you cannot break it. But *why* can't you remove it? Even screensavers don't depend on this nowadays (just tried it. Start sesson with xgrab.so workaround. Lock Screen. Press Alt-F2. Nope, this *doesn't* bring up a command prompt, screen stays safely locked.) > In fact currently there are proposals to add exactly this to Wayland to allow > backward compatibility. One more reason not to move over to Wayland... But seriously, what kind of *useful* functionality is this supposed to bring? I mean, useful to the user, not to advertisers, marketers, spammers and scammers... -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=383052 --- Comment #6 from Alain Knaff --- Indeed, it seems to be XGrabKeyboard that they are doing, thanks for the pointer. The workaround at https://bugs.freedesktop.org/show_bug.cgi?id=21652#c4 succeeds in addressing the issue, without any negative side-effects. I'm just wondering why such disruptive functions still exist in the X API :-( -- You are receiving this mail because: You are watching all bug changes.

The X11 protocol allows applications to grab keyboard input. This is a standard feature of any context menu. The general pattern is to release the grab as soon as one clicks outside the context menu. Firefox is not doing that apparently. I'm sorry, but we cannot do anything about it on X11. -- You are receiving this mail because: You are watching all bug changes.
