Version: unspecified OS: Linux Leaving a resource with a contextual menu open leads to a screen locker + contextual menu shown on top. Trying to unlock the screen for the first time will fail, the second time will succeed but you'll get a gray window with no content (screen locker?) covering all the screen and no peek area for some seconds. This happens on 2011-10-18-00-53-meego-plasma-contour-in-progress-USB-live.is Reproducible: Didn't try Steps to Reproduce: 1. Long tap on a resource to get the contextual menu 2. Leave the device running for some time 3. Once you see the screen locker, try to unlock it 4. Observe the result (the contextual menu might be displayed before unlocking) Expected Results: The contextual menu should not be displayed on top of the screen locker.
I'm not sure how the context menu in Plasma Active is implemented but if it is a normal Window, I am sorry to say that this is a well known and common limitation of the X Windowing System: it is impossible to lock the screen while a context menu or a normal menu is shown. Reason: the context menu performs a keyboard grab which means that the screen locker cannot get the grab and refuses to lock the screen.
Well, in my case the screen was locked (or it looked like that).

Plasma Active is no longer under development. (Martin's comment about screen locking is still relevant in X11, I think, but doesn't apply to the unmaintained-product Plasma Active)
