How to apply specific scalings to a specific window?

Translated from Chinese

My monitor's scaling is 1.6 and the resolution is 2560x1440. But when I opened Minecraft, the game showed a resolution of 3200x1800. This means that my game has been scaled as well. Since this usually affects frames per second, I'd like to set scaling of 1 for this window separately to revert back to a resolution of 2560x1440. Is there any way I can do this or the same? Appreciate!

considering that, I assume it's running in native wayland. No, there is no way to get around this, unless the app itself supports the fractional scaling protocol.

GLFW uses the fractional-scale-v1 protocol to implement fine-grained framebuffer scaling. If the running compositor does not support this protocol, the GLFW_SCALE_FRAMEBUFFER window hint will only be able to scale the framebuffer by integer scales.

Minecraft uses the library of GLFW, so I think that it should support fractional scaling.

depends. Commercial apps have a history of using very outdated dependencies. At any rate, this is not a hyprland issue. All other apps scale fractionally :)
