The menubar selection lacking round corner when I tap () button.

Hi everyone,

I don't know why my MacbookPro 16" 2021 occurred the issue regarding to selection shape in MenuBar.

In brief, I have set up my new MAC (Ventura 13.6.3) and tried connect to a Monitor via HDMI port. It's worked perfectly but after unplugging the cable, I got the UI bug below:

Before changing Display to MoreSpace, the left corner of selection was rounded.

After connecting to extend monitor in Display MoreSpace, I realized the selection area like squared.

No mater what I have done by changing display resolution, it's still squared. Please take a look to help me how to revert it.

Thank you in advance.
