It is as designed, since the default output size uses the native viewport from the emulated hardware output.

Either disable the extra stuff outside of the native video output in the internal menu, or use alternate renderer in the libretro menu to set output resolution as whatever instead of native resolution.

Thx for your answer @sonninnos However Removing the keyboard or led section, changing the aspect ratio or changing the output resolution is not fixing the issue. :(

I meant the core option, not any frontend aspect ratio or resolution.

Alternate render with large enough resolution versus native shows clear difference in the menu drawing also:

Native:
