My primary screen has high DPI, while my secondary screen has normal DPI.
If I open the About screen on the high-DPI monitor it looks fine. Same thing if I open it on the high-DPI monitor and then drag it to the normal-DPI monitor.
But if I have Verbum on the normal-DPI monitor, and open the about screen, most of the time it renders incorrectly. It does things like this:

I think it has to do with the positioning of the About Window on its initial load. For whatever reason, when I have Verbum open on the second monitor, the About Window is opening halfway between the primary and secondary monitor, and partially offscreen on the bottom of the screen. The parts that render incorrectly are the parts that are off-screen, or that cross between monitors.
Here's a log where the only thing I do is open up Verbum, full screen it on the second monitor, and open the About box.
