Mouse cursor inconsistent in Firefox and Waybar

[ocharles]

Hi all.

I have the following in my Niri config:

cursor {
    xcursor-theme "breeze_cursors"
    xcursor-size 24
}

When my mouse cursor is over my desktop, or a kitty terminal my mouse cursor is Breeze, an expected. However, when I hover over a Firefox window, or my Waybar, I seem to have a default cursor that's smaller. Does anyone know what could be causing this?

Firefox and Waybar use GTK 3, it probably has a different idea of where to load the cursors from than the XCURSOR env variable. You'll need to look into GTK 3 settings I guess

Thanks, I didn't know that. Reading https://wiki.archlinux.org/title/Cursor_themes#GTK suggests I should look at ~/.config/gtk-3.0/settings.ini, and indeed:

❯ cat ~/.config/gtk-3.0/settings.ini 
[Settings]
...
gtk-cursor-theme-name=Breeze_Snow
gtk-cursor-theme-size=24 

doesn't match Niri. I'll update that and make them consistent - thanks!

Actually it seems that my GTK apps aren't loading the cursor at all - it's neither breeze_cursors or Breeze_Snow. Nontheless I know this is a GTK think, so I'll accept this answer and do some digging.

Maybe nwg-look would help you.

Ah nice! I'm not sure what I changed but after tweaking that ini manually and using nwg-look, and probably restarting my session, I'm all sorted.
