Illustrator window is bordered with red
In some cases, Illustrator shows a red line around the window.
I run Illustrator 23.0.4 on MacOs Mojave 10.14.5
I don't want disable GPU performance to hide it, I will lose performance doing so.
I think it's a glitch, because if I press "F" two times, the red line it's gone.
Thanks

I recently upgraded AI 2020 (24.0) to use the overprint preview function and then turn it off. Sometimes this problem occurs.
