Okular's Desktop icons & thumbnails tiny after abrupt power off

[Francesco Gerotto]

Hi all,

I hope this is the appropriate channel to ask about this. If not, please
address me to the correct branch of Support.

I recently started having issues w/ the way Okular's icons and thumbnails
are displayed on my desktop. I believe the incident followed an abrupt
power off of my laptop. I am running Windows 10 pro on a Lenovo T460s and
downloaded Okular from Microsoft Store.

Icons and thumbnails are now tiny compared to other desktop icons. I am a
layman and asked AI (specifically Qwen2.5-Max) for help troubleshooting the
issue. Below is a list of attempts:

   1. Cleared all iconcache_*.db and thumbcache_*.db files from
   %LocalAppData%\Microsoft\Windows\Explorer (this required booting my laptop
   in Safe Mode);
   2. Clean uninstall (including removal of all residual Okular files from
   %LocalAppData% , %AppData% , %ProgramFiles% and %ProgramFiles(x86)%, as
   well as clearing Registry Editor) and re-install of Okular (via Microsoft
   Store);
   3. Run a sfc /scannow;
   4. Since none of the above yielded results, I looked for solutions
   related to scaling. In fact, I am currently using a 175% display zoom and
   on 100%, while all other apps and screen in general are tiny, Okular's
   desktop icons are finally proportional to the rest. This prompted
   5. Adjusting High-DPI Scaling Behavior for Okular via Properties >
   Compatibility on okular.exe (overriding high DPI scaling behavior to System
   and System (Enhanced)). Playing around w/ this achieved imrpoved desktop
   icon scaling, but framed each icon as well as rendering tiny all the layout
   of the app once launched. I therefore restored to the original settings.
   6. Updated firmware and drivers.

I do not now of other attempts left to solve this issue. Has anyone an idea
of how to troubleshoot this?

Happy to provide any details necessary.
Thank you for your help
