New crash information added by DrKonqi

gwenview (21.12.2) using Qt 5.15.3

- What I was doing when the application crashed:
After testing, I found that repeatedly entering and exiting fullscreen mode by double-clicking will always crash Glenview when viewing a JPEG file. Interestingly enough, repeatedly entering and exiting fullscreen mode on a PNG file will never crash Glenview.

Crashing may be limited repeatedly entering and exiting fullscreen with JPEG files, not affecting PNG files.

Comment 3 A Linux User 2025-08-17 12:37:41 UTC

Cannor reproduce. Both jpg an dpng works fine with spamming doubleclick for fullscreen. Can you check again?
