Window overlapping behavior....

[celestian]

I have noticed in FGU some windows have issues with overlapping in windowlists?

Here is a non "inspect" view where you can see shading line is again wrong.

The same window in FGC looks fine:

As with many of the deep issues that you have found and show pictures of, I have no way to easily set up or test this issue (as no other code is doing exactly what you are doing).
Please provide example extension and data to show the issue for faster identification and fix.
