Can't reproduce.
Comment 2 Ismael Asensio 2023-01-17 15:04:44 UTC
The screen recording suggest that either the screen is small (smaller than 15" laptop at least :D) or there is some scaling applied.

Could you please provide this info (screen size and scaling factor) so we can try and reproduce it?
Thanks!
