How to disable scaling when watching videos, playing games in fullscreen

[Schweber]

I have a 4k display that i've set to scale to 1.5 to make it more legible.

However, when i watch a video or play a game in fullscreen, i would like to see it in 4k and not in the lower resolution that is scaled up.

Is there a way to do this?

Clients that support the fractional-scale protocol will already show you the full resolution, like mpv for videos, and running games in gamescope. Otherwise you could bind niri msg output "yourname" scale 1 and vice versa.
