Created attachment 111743 [details] Valgrind log I opened a video file, entered full screen, exited full screen and close the window. I did noticed that while in full screen the window was not filling the screen entirely, i still could see the bottom panel on the desktop.
Dragon Player not entered in fullscreen after double click on video - but the button 'Full Screen' changed into 'Exit Full Screen' - after subsequent double click on video - Dragon Player crashed with signal stopped Plasma: 5.12.4 Apps: 17.12.3 Frameworks: 5.45.0 Qt: 5.10.1 Kernel: 4.14.34-1-MANJARO OS: Netrunner Rolling Video: Intel 4400 Driver: xf86-video-intel 1:2.99.917+823+gd9bf46e4-1 Screen: 1600x900 wayland-protocols 1.13-1 wayland 1.14.0-1
dragon 18.12.1 is still crashing when I leave fullscreen mode under Wayland on Arch Linux.
For dragonplayer-20.07.70 i don't have this problem anymore, maybe it was fixed for an earlier version but this is the one i used when restesting for this bug.
