Screen shot of view panel with missing thumbnail images...
SUMMARY
Occasionally one or more thumbnails will be missing from the view panel.
STEPS TO REPRODUCE
1. Create a new folder, set view mode to "Icons" and enable "Show previews".
2. Copy a few images to the folder. (At this stage all thumbnails are correctly
generated and shown).
3. Close Dolphin.
4. Relaunch Dolphin and navigate to the folder created.
OBSERVED RESULT (Occasionally)
One or more thumbnails are missing, (the generic icon is shown in it's place),
as shown in the attached screenshot.
EXPECTED RESULT
All thumbnails are correctly shown.
SOFTWARE/OS VERSIONS
Linux/KDE Plasma: openSUSE 20181224
KDE Plasma Version: 5.14.4
KDE Frameworks Version: 5.53.0
Qt Version: 5.12.0
ADDITIONAL INFORMATION
These missing thumbnails have been generated and can be seen in
~/.cache/thumbnails/normal
This appears quite random, it's not restricted to certain image(s), and/or
folders. The thumbnail/preview is always shown correctly in the Information
Panel.
I've tried deleting all thumbnails from ~/.cache/thumbnails/ It matters not if
there are only a few thumbnail images, or several thousand.
Whilst viewing the folder containing the missing thumbnails:
Using refresh (F5) or toggling "Show previews" does not result in the missing
thumbnails appearing.
Changing view mode from "Icon" to either "Compact" or "Details" and then back
to "Icon" will cause the missing thumbnails to be correctly displayed. If
Dolphin is the closed and reopened there may again be missing thumbnails,
although not necessarily the same one(s).
