@CShubert Thanks for the tip! Yes, even though I didn't use any tweakers that would modify Windows UI, I think I found the culprit: I had an outdated version of the Lazy Nezumi plugin installed, which was causing problems with the taskbar in the latest Photoshop version while working in the background.
