I can see what the problem _might_ be, but what’s interesting is that it doesn’t cause any error for me. The icon it’s looking for is called `flowtop_compright.png` in the actual folder - so I’m guessing it’s because it’s looking for it with capital letters and therefore not finding it.

If you navigate to this location:  
`/usr/local/lib/python3.8/dist-packages/psychopy/app/Resources/light`  
and change the filename to match what’s in the error (`FlowTop_CompRight`), does it fix the problem? If so I’ll just rename the files for each theme in the repo and that should solve it for other `pip` users!

I encountered this same problem. Capitalizing the names of the files fixed the problem. Given that his has happened at least twice, should an issue be submitted on GitHub?

The issue is fixed on GitHub since this commit: [BF Case Sensitivity on Linux · psychopy/psychopy@b52ba31 · GitHub](https://github.com/psychopy/psychopy/commit/b52ba31e0c9dbc187a2d2b7a932607884324b766#diff-f7e54a3a183cc568c4175c7382604d6631c1733e169593939943e44c025980f1)  
but that was 10 days after the most recent release. It will be included in 2021.2.0 in a few weeks time
