Hello I found this borderless fullscreen macro which does seem to work with diablo 4, but when I use it my mouse if offset in the y-axis by the size of the windowed mode bar a the top I believe. the x axis is fine cause there is almost no bar offset there but it might be off by a few pixels. Is there a way to fix this in the function?

This one works on WoW but not diablo 4. But the mouse doesnt have the offset issue.

Is it your mouse clicks that are offset from the actual pointer?

Yes the mouse click is off from the pointer by (x,y) amount x and y being the about the border size it got rid of.

Like if I had my mouse on top 1/2 of the 'Delete Char' button it would be highlighting the 'change world tier button instead'

Example screenshot the 'change world tier' Clickable area would be about the blue box I added to the screenshot from the tip of the mouse cursor. without the function it stays within its normal box.

We took a look into this but it doesn't look like it's something we can fix unfortunately, sorry!
