--- Comment #37 from Alexander Nolting <a.nolt...@almano.de> --- I don't know if it's helpful but I had seen some strange behavior of applications (and the whole plasmashell) after unlocking the screen while the screen was switched of by power management. It looks like that sometimes the whole opengl buffer/memory/context is corrupt for the shell or only for one or two applications that are still open. For instance this morning was konsole open together with firefox, yast and dolphin. The screen were locked and background light seems to switched of for both internal screen at my laptop as well for the via DisplayPort/Thunderbold port connected external Samsung display. I moved the mouse and the xserver seems to be restarted 2 times while trying to wake up for the internal and then the external screen. While this happened the internal screens shows a bit earlier content and I noticed again the same flickering for plasma and for a very short period of time I could see content from the desktop even while the screen was in locked mode and I had not entered any password at this time (due to another issue which klockscreen functionality, which randomly routes the focus of the password textbox while the xserver is waking up). And the app window of konsole was at this already damaged as it showed, formed in triangles, parts of the desktop background instead the bash content. And this application were also damage after I entered my password and the desktop were unlocked again. I needed to close konsole and restarting it to use it again. And there is a similarity to the bug 344783 - https://bugs.kde.org/show_bug.cgi?id=344783 - which I opened after I moved to plasma5 last year. In this bug I had the feeling, that the issue handled in this bug only happened while the external screen was attached and I was at this point on kernel 4.2. The issue disappeared on 4.3 and now, after I updated a couple of days before to kernel 4.4.0-2, the issue appears again but not with these great effects.
