Custom resolutions from the unified launcher can cause several issues when Minecraft Java Edition is booted up
Repro steps:
Boot launcher
Log in
In Java "Installation" tab, add a new version to be installed.
Change the resolution in "Create new installation" window to the highest recommended (2560x1440) or set your own.
Create the Java version and boot it.
Observe as the loaded Java Title is displayed incorrectly, with unresponsive buttons.
Observed results:
Changing Java version to a custom resolution in Installation tab may cause several issues of the game window.
Issues are the following:
Game window is displayed in the corners, cut out of the screen area, which User may not be able to resize or move.
Buttons of the Title are unresponsive or have their trigger misplaced.
Both outcomes may happen at the same time.
Unresponsive buttons confirmed to occur more frequently on macOS.
Since the issue occurred on mac device with High-end monitor we assume this is not an issue related to the hardware.
Additional Info:
The following Java resolutions have been tested across the platforms:
2560x1440
2560x3000
1234x4321
1440x2560
Expected results:
Custom resolutions set for Java versions are fully functional and are displayed correctly.

Yeah, it still happens. Video demonstrating this issue on a UHD monitor set up on 200% scaling (default of MacOS, "Looks like 1080p" according to display settings)
I was able to reproduce in 21w16a with the custom resolution of 2560x3000 buttons became unresponsive and triggers to go to a different part of the menu was misplaced for me
