Video bug on vertical monitor #94
Description
When I move the epub-checker window to my secondary monitor that is rotated 90° it won't consistently display the contents without glitching. I tried to take a screenshot but it magically fixes itself when I do so. So I took a photo.
OSX 13.6 Macbook Pro M2 with ASUS VY249 in portrait mode. It also did this with my old Mac Mini intel 2019 running OSX 12.6.
