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
