SUMMARY

This particular picture is displayed incorrectly in Gwenview. It's upside down

Same thing as here: https://github.com/immich-app/immich/issues/8355

I'm not sure that this is actually digikam issue. Dolphin preview is also upside down, but digikam (8.5.0) displays it correctly

Comment 3 John Kizer 2025-01-27 20:08:31 UTC

Hi - thanks for the bug report! I can reproduce on Fedora KDE 41, Gwenview 24.12.1.

I'm not sure if this is further upstream - there is a Qt bug related to this topic, https://bugreports.qt.io/browse/QTBUG-121496 , but I don't know if it's applicable here.
