Mixed up icons on Niri

I'm in the process of transitioning from KDE to Niri, and I've run into an issue.

For a bit of background: While I was tinkering with the setup, I set the QT_QPA_PLATFORMTHEME environment variable in a way that it affected both desktops, which had the side effect of messing up the icon theme on KDE. This is the first time I had this sort of issue, but has since been fixed.

My current issue is that on Niri, the icons are messed up in the same way that they were on KDE; essentially what's happening is that different icons are being displayed than the ones that should be in some cases, but not others (even within the same app). I've looked around my file system for anything else that might be trying to set the theme, which is what caused the issue on KDE, but I've come up empty, so I'm not sure what's going on here. I'm using qt6ct for themeing.

Re: Mixed up icons on Niri

Try

gsettings set org.gnome.desktop.interface icon-theme "your theme"

Which worked for me...
