Description Ilya Bizyaev 2024-10-24 19:21:23 UTC

STEPS TO REPRODUCE
1. Click the "Add an attachment" button on this page, then press "Choose a file".
2. Make sure that the preview sidebar is displayed (F11).
3. Move your cursor over various files.

OBSERVED RESULT
For many files, no preview is displayed, even though they have a thumbnail in the main view.

EXPECTED RESULT
If a file has a thumbnail, it is always displayed in the preview sidebar.

SOFTWARE/OS VERSIONS
Operating System: openSUSE Tumbleweed 20241021
KDE Plasma Version: 6.2.1
KDE Frameworks Version: 6.7.0
Qt Version: 6.8.0
Kernel Version: 6.11.3-2-default (64-bit)
Graphics Platform: Wayland

ADDITIONAL INFORMATION
I attached an example image that gives me no preview in the file picker, even though a thumbnail is successfully generated for it. Also, Dolphin's preview panel (F11) does not suffer from this issue.

Can you figure out a pattern behind which files don't get proper previews?

Comment 3 Ilya Bizyaev 2024-10-28 12:15:16 UTC

Can you reproduce the issue with the attached file?

Comment 4 Nate Graham 2024-10-28 15:04:19 UTC

Yep, I see a preview for it as expected.
