HighDPI folks: I have 2x24 monitors here. Is it possible to manually set the DPI for one of them in Windows, so I can try to reproduce this bug? Or do I have to have an actual HighDPI monitor?

re comment 3: Yes, you can set a higher scaling in the display settings without actually having a high DPI monitor. The maximum scaling allowed for a 1080p monitor is 175%. For 1440p it's 225.

Having 2 24" monitors with different scaling is a trippy experience.

One interesting thing I've noticed is that the windows opened on the high DPI monitor will not have the broken behavior. It only happens when the window is moved into the high DPI monitor. I looked at this briefly and the PDF plugin appears to be receiving the wrong coordinates.
