So upon further investigation it turns out that the drawing of the wobbled window (is that a thing) is being drawn much further out. It is odd that this only seems to happen with mIRC and Task manager. Explorer windows, all browsers, and pretty much all UWP apps I've tried seem to work fine. It also only occurs on my lower satellites and not the main display.
In this video you can see that while moving a window if you move far enough out the window will become visible with the cursor many pixels away (perhaps the size of the window's distance worth based on the target monitors DPI?)
The bottom two are both 1080 @100% while the top Main display is 4k @150% (I also tried setting it other values such as 100% etc... with no change).
