Same in 1.20.4 https://bugs.mojang.com/browse/MC-251353?focusedId=1316680&page=com.atlassian.jira.plugin.system.issuetabpanels%3Acomment-tabpanel#comment-1316680
Did not realize this was a newer code change compared to previous versions.
This is basic behavior in Minecraft itself, not a hardware/OS issue.
Main menu is always 60 FPS despite the game's graphics settings.
Would be nice for the main menu to run at whatever is configured.
OS : Arch Linux
Minecraft Java 1.20.4
