also that video should not have any audio, the culrpit video, it was an accidental overlay

it still happens on pre-release [1.21.9] 4

tried this on another world and its the menu blur causing the menu lag issue

I hope this is fixed…

1.21.9 Pre-Release 2 has this problem as well… But, I have found something else that is interesting…

this is to show its not affecting in the main menu, only when I’m in a world.

this is after i reinstalled the graphics driver

whats even stranger is that ONLY the visuals, (the white outlines) on the options look extremely delayed but as if I pressed them normally

I have reinstalled the latest applicable graphics driver, it still has the same issues

because when i tried to play the game in fullscreen mode, pressing the escape button doesn’t lag the game on fullscreen…

i think I found out how the bug happens, likely in by not going full screen mode.
