I have some Hi-DPI devices, which work fine most of the time with display scale settings. But when it comes to video games, the display scale makes them blur, especially on handheld devices like the PinePhone.
And sometimes I just want to scale 3D games to increase FPS, since reducing system display resolution can make my desktop icons messy, it will be convenient if I can simply scale its window.
So I tried to launch a nested Weston, set its scale ratio to 2 and launched Minecraft JE, but it seems that the game couldn't grab the pointer.
Is it possible to set a per-application scale ratio?
