What I've already tried: reinstall qt5-default packages, update them. Memtest showed RAM is fine, GSmartControl shows no problems in my SSD drive.
Comment 2 Pedro 2025-04-06 23:54:56 UTC 
Thank you for the bug report. I was not able to reproduce this bug in Gwenview 24.12.2. May we ask you to please check if this is still an issue with Plasma 6.3.2 and Gwenview 24.12.2?
