Sometimes windows will just look like this? Minimizing or changing tabs usually fixes it, sometimes resizing. If I select a folder or a menu option it usually looks normal while highlighted. Happens most often with folders and with the software manager. Also happens to the text in Nicotine+ sometimes and the text editor. Never seems to happen to Firefox or VLC. I don’t even know what to call what is happening visually here so I haven’t been able to find anything just by googling.
