I didn't see this in the list of known issues, so posting (though it's likely another symptom of the hidden border issue listed elsewhere).

I use hotkey functions to move my windows to different places (Monitors 1 and 4 are portrait, 2 and 3 are landscape). So, for example, I have "move to monitor 3, move window to top-right corner, change width to 50% and height to 100%. In theory (and prior to Windows 10), this would move the window to the right half of monitor 3.

Now, however, there's a sliver of window that extends onto the next monitor to the right. Using the Windows hotkey Win-RArrow will make it fit properly, also moving it over a bit to the right (it seems the DF function also hangs over a bit to the left).

It's as if 50% isn't really 50% any more. Changing the function to 49% till hangs over into the next monitor to the right, but leaves a gap in the middle of monitor 3.

It doesn't make a difference. Tried it both maximized and not.

Sorry, been traveling.

All applications I've tried it with.

7.3 b2 fixed it.
