IntelliJ IDEA 2024.1 (Ultimate Edition) UI Bug

Hello, 한남일. Could you please check if the issue persists if you disable the UI theme you use?

There is a new setting “Centered Editor” in "Material Theme UI" plugin causing this editor layout issue. Unchecking this option will revert to the proper layout.

Alemargo00, yes, looks like so, but it's better to check anyway. 

I solved it thanks to Alemargo00.
