Hi, I have a pretty low end machine, and I play Minecraft on it, So to improve framerate I set my in-game resolution to 576p, to still get a 16:9 ratio and good framerate. I had 0 issues until a few days ago. My resolution was set to a really weird resolutio: 1008p, I didnt set it to this resolution so I had no clue, I tried it on other resolutions to see if it affects those one as well, the only one that works is 1080p, but it kills my framerate, When I set it to 720p the resolution switches to 1280p, I provided screenshots, I hope there is any way to fix this.
Thank you.

I can confirm this, setting the Fullscreen Resolution to 1920x1080 sets it to 2566x1512 on a 4K screen, definitely something off going on.
Cannot reproduce in 1.20.1 with a 1440p monitor on fullscreen. Resolution changed as expected for me when using the slider.

I'm seeing the same or a related problem with Minecraft Java 1.21.1 with KDE Plasma 6, plasmashell 6.1.5, kwin 6.1.5, Wayland session, Linux kernel 6.11.2, AMD Radeon Graphics (radeonsi, renoir, LLVM 18.1.8, DRM 3.59, 6.11.2-0-edge) (0x1638) with Mesa 24.2.4. I'm not using mods since this is a fresh install of Minecraft.
When I go fullscreen, then use the slider, then press "Done" at the bottom, the mouse is immediately offset in a very incorrect way. It seems like the game thinks something changed. However, the resolution stays the same and seems to be the native screen resolution still.
When after that I toggle to windowed and then back to fullscreen, the mouse offset is correct again but the slider now still shows a low resolution while I'm still using the high resolution.
In conclusion, whatever function is actually changing the screen resolution doesn't seem to be working.
Please make sure you exit the menu by pressing "Done" instead of using "ESC" key
