"Fullscreen Resolution" scaler does not work correctly, instead the game is displaying at a much higher resolution than the settings say

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.
