Revu is the only program on my machine that has this issue wherein the program's borders frequently exceed the Windows border. Be this when I maximize the program, tab over, or pull a PDF tab out and into the frame of a second monitor to maximize it on a different screen. My monitor boundaries are set correctly, the program is up to date, and - again - this is the only program that does this on my laptop.
It occurs on more than 3 monitors, different resolutions, different refresh rates, and both with and without a doc station. I've exhausted all Windows 11 troubleshooting that I can find related to application boundaries; and since it's only Revu doing this, I now suspect this is a problem with the Revu program itself.
If you experience this issue, it is quickly fixable using Shift + Windows Key + Arrow shortcut to force the program into a corner (thus correcting the border) which can be maximized again. However, a known permanent fix for this would be appreciated.
