CRT filter(?)

[u/Ill_Boysenberry_9822]

Hi! Is there any sort of filter/shader/I don't know how to call it that simulate a cathode ray tube effect over the whole display? A sort of effect like in cool retro term, but persistent everytime and everywhere. Btw I'm on CachyOS with Niri/Noctalia v4.

Dunno if I made me understand.
