SUMMARY
I have two screens. First is laptop 1920x1080 screen with 125% scaling, second is my external 1920x1080 screen with 100% scaling. When I use "Apply scaling themselves" in Legacy applications (X11) all scaling in apps is ok except Minecraft, it becames blurry. If I set "Scaled by the system" in Legacy applications (X11) minecraft looks ok like it should be, but xwayland apps on 125% scaling screen looks blurry. Also I faced that Minecraft has max resolution 2400x1350 while facing this bug

STEPS TO REPRODUCE
1. Have two monitors with 125% and 100% scaling
2. Have "Apply scaling themselves" option ticked in Legacy applications (X11) in Display Configuration section.
3. Run Minecraft (1.20.6)
4. Face blurry Minecraft

OBSERVED RESULT
Minecraft runs blurry and has 2400x1350 resolution as highest possible

EXPECTED RESULT
Minecraft should run at clean resolution and have 1920x1080 resolution as highest possible
