Error of rendering in menu bar

I'm experiencing rendering issues when opening a second project tab in IntelliJ Ultimate, and I had no idea how to fix it. The layout of the menu bar just bugs out, and I can't click on any of the settings, but below, I can still code, write, and navigate through the folders normally.

In case anyone else is having this problem, simply repairing the IDE was enough to resolve it (I had to create a shortcut in Keymap → Others → Repair IDE to perform this action). But I'm leaving this note here as a solution for the bug and in case anyone else is facing the same issue.
