# sway scaling

The purported solution to hidpi when working on modern linux with Sway/Wayland would be to set the native resolution and then apply scaling.

This can be done with the display configuration, for example:

	output HDMI-A-1 scale 2

So if you set your resolution to 4k then scale to 2, you render at 1080p.

This keeps things on the screen sized for you to be able to read them.


## problems

This can have unintended consequences on games and game performance.

In particular games that rely on xwayland may experience performance degradation.

Some issues include screen flickering, as well as erratic crashing.

Oddly when mangohud is enabled you may see the hud flicker too, indicating it's a problem with the parent window and not the game itself.

Granted, because the render dimensions are upscaled you may also see a performance benefit.

If you find some games have a problem, you may consider disabling screen scaling when playing them.
