Expected Behavior

I have three 1920x1080 pixel monitors.

If you re-scale the Windows Display UI from 100% to 125%, it should ideally retain the nominal coordinate system of 1920x1080.

Right now, it re-scales to 1/1.25 or 1536 pixels wide. But it still anchors the next monitor coordinates at (1920, 0) in the top left corner, so as you move your cursor across the monitor boundary the coordinates jump directly from x=1536 to x=1920 and ~400 pixel coords get jumped.

Current Behavior

I have three 1920x1080 displays.

In Windows, if you re-scale the System Windows UI to be 125% larger, the coordinate plane in Region Switcher will become 1/1.25 smaller or 1536 pixels in width.

Region Switcher will consider Display 1 to go from (0, 0) top-left corner to (1536, 0) in the top-right corner. The guide lines report the pixel coordinates from [0...1536].

However, it still anchors the 2nd display at (1920, 0). And the cursor coordinates will jump from x=1536 to x=1920 as it crosses the monitor boundary.

So the coordinate system is skipping ~400 pixels whenever you move your cursor across a monitor boundary if you re-scale the Windows Display Settings UI to a setting of 125%.

Steps to Reproduce

Change your Windows UI scale to 125% in System Display Settings.

Anything else we should know?

You can easily work-around this if you know what's going on, but it was very confusing at first. I'm otherwise enjoying the plugin, thanks!!
