OS modal windows (upgrade available, error occurred, background operation finished, unsolicited tip) that spring up unexpectedly, stealing the keyboard focus, and are accidentally accepted or dismissed because you happened to be typing — perhaps not even looking at the screen, or at *that* screen: how #$% is this still a thing? #usability #antipattern

For me, it's #Ubuntu #GNU/Linux. But I'd be (pleasantly) surprised if it didn't happen on other OS's.

Those #modals should have a little timer, or perhaps wait for more deliberate interaction (like mouse hover / ⇥, then Esc / ↵).
