SUMMARY *** I can not reproduce this consistently, but found a way to make it happen with about 50% consistency: Being on a tablet and using touch is essential here I think. *** STEPS TO REPRODUCE 1. Open Okular and maximize it 2. Open a PDF file 3. go to the next workspace via three-finger-touch-swipe 4. Rotate the tablet to be vertical and in touch mode 5. three-finger-swipe back to the workspace with Okular in it OBSERVED RESULT Not always, but often times, the document area becomes transparent and a bunch of glitches appear, see attached video EXPECTED RESULT No visual glitches, the document gets shown in a vertical Okular window SOFTWARE/OS VERSIONS Operating System: Arch Linux KDE Plasma Version: 5.92.0 KDE Frameworks Version: 5.248.0 Qt Version: 6.7.0 Kernel Version: 6.7.1-arch1-1 (64-bit) Graphics Platform: Wayland Processors: 4 × Intel® Pentium® CPU 4425Y @ 1.70GHz Memory: 7.6 GiB of RAM Graphics Processor: Mesa Intel® UHD Graphics 615 Manufacturer: Microsoft Corporation Product Name: Surface Go 2 System Version: 1
Created attachment 165262 [details] Screen recording of the glitchy okular window
(In reply to Tammes Burghard from comment #1) > Created attachment 165262 [details] > Screen recording of the glitchy okular window It also happened without plasmashell crashing, but the shell crashed a lot while I tried to consistently reproduce this, so I did not bother to retry until I get it without crash.
Hello, I am experiencing this bug regularly too, it looks the same as in recording. It seems to be happening after some time, I don't change my screen orientation at all and plasmashell hasn't crashed for me. It might be related to changing the workspaces/desktops with three-finger-touch gesture, but it might as well not be related. I have also had it happen after waking my laptop from sleep. I usually have multiple instances of Okular open. I can recover normal behavior by zooming in or out with the two-finger-touch gesture, but over means of zooming don't seem to work.
