When I hold Alt and press Tab, the window switcher goes through the applications in the current desktop, however, sometimes (I don’t know how to replicate it) when it reaches the last one, it does not cycle back to the first. When holding shift (going backwards) it does cycle correctly.
Relaunching the computer sometimes fix it for a while.
I’m using Budgie version 10.9.1, Ubuntu 24.04.3 LTS. I have not changed any config for the window switcher as far as I know.
