Summary
Digikam Qt6: Full-size image preview fails ("Impossible de charger l’image")
while thumbnails work; Qt5 works fine on same system
Description
I compiled DigiKam from master using Qt6 and KF6.
The application builds and runs correctly, thumbnails are generated and
displayed normally.
However, opening an image in the main viewer or full-size preview consistently
fails with the message “Impossible de charger l’image”.
The same images work perfectly when DigiKam is built against Qt5 on the same
machine.
Steps to Reproduce
Build DigiKam against Qt6 (KF6)
Launch DigiKam
Browse to any folder with JPEG images
Click on an image to open full preview
Expected Result
Image should display in full size.
Actual Result
Error message: “Impossible de charger l’image”.
Thumbnails are still displayed correctly.
Tests Performed
Disabled OpenGL
Disabled hardware acceleration
Forced software rendering
Restarted DigiKam
None of these change the behavior.
Additional Information
Same images
Same system
Same DigiKam version
Qt5 build works perfectly
This suggests a Qt6-specific regression in the full image rendering pipeline.
digiKam: 8.9.0
