This began with plasma 6.1. Selected folders are now black, I think they were dark blue when selected. ( programming.dev )

Try deleting or renaming ~/.cache/icon-cache.kcache

I'm also experiencing this bug, regardless on which theme I set (Breeze, Breeze Dark, Breeze Dark EndeavourOS, Breeze Twilight). The folder icon is the only one with this problem, and only when the window has focus

Can not reproduce with stock Breeze theme on Arch

Are you using the default Breeze theme?

I've heard such issues can arise with 3rd party themes, so I just stick to Breeze. I'm using Breeze Dark and I have not seen this issue on Plasma 6.1.
