SUMMARY STEPS TO REPRODUCE 1. use eclipse IDE 2. make the content assist crash by entering '.' and CTRL+SPACE (this stage is random) 3. This will make the ui freeze in some case (The application window became pale in my case) 4. try to move that frozen window or to close it with the mouse button 5. In my case after one try the system ui was not responding to mouse movements And the keyboard was not responding any more, I had to restart my entire system. OBSERVED RESULT No screen shot could be taken since the system froze. EXPECTED RESULT The crash one one application's UI should not be the cause of a full system freeze. SOFTWARE/OS VERSIONS kwin RPM version: kwin-5.20.4-2.fc33 ADDITIONAL INFORMATION
If kwin is frozen, we're going to need a backtrace of the frozen kwin. The easiest way is to ssh from another machine or phone ssh client and sudo gdb --pid `pidof kwin_wayland` "bt" and attach I'm afraid it's very hard for us to do anything otherwise.
Thank you for the advice I will try this if i reproduce the bug.
