Update 93.0.4585.21 and finally this issue is fixed! Thanks Opera dev!

Update 89.0.4447.48, still not yet fixed.

I used to be able to slide my mouse cursor to the top of the screen above the 'open a new tab' button to click it (Opera is maximized). With the current Opera version 89.0.4447.48 I have to lower my mouse cursor a few pixels from the top of the screen to be able to click the 'open a new tab' button.

I can click the Opera menu button, the tab selectors, the search tab button, the minimize button, the restore button, the close window button from the top of the screen. Only 'open a new tab' can't be clicked from the top of the screen.

Google Chrome's 'new tab' button can be clicked from the top of the screen. Firefox's 'open a new tab' button can be clicked from the top of the screen. Older version of Opera's 'open a new tab' button can be clicked from the top of the screen.

@burnout426 Thank you for the information. Is the bug list open to public? Where can I see DNA-100196?
