Does it still happen if you uninstall "qt5ct"?

Comment 2 Austin Kilgore 2020-10-21 03:18:24 UTC

(In reply to Christoph Feck from comment #1)
> Does it still happen if you uninstall "qt5ct"?

I uninstalled qt5ct and filelight does indeed work with qt5ct removed.

Since filelight is the only program experiencing this issue I'm inclinded to think it's a bug with filelight and not qt5ct. I have a lot of programs that rely on qt5ct to function correctly so removing it permanately isn't a option for me.

Also, I came across this which might be a duplicate https://bugs.kde.org/show_bug.cgi?id=415732
