(LM21) Broken titlebars when snapping.

[JulianHeuser]

Describe the bug
Snapping a window then unfocusing it causes the titlebar to appear offset. This doesn't happen with gtk stuff (calculator, calendar, etc.), only programs with a standard titlebar.

This bug comes from my Mint-Yz or their Mint-Y ?
This doesn't occur with the Mint-Y theme.

To Reproduce
Steps to reproduce the behavior:

1. Open a window (file manager, terminal, etc.).
2. Snap it to the side or a corner.
3. Unfocus it by clicking somewhere else.

Expected behavior
A clear and concise description of what you expected to happen.

I know. These Mint-Yz are not ready for LM 21. I must do a major update from the upstream source. I will be working on this later this month...

Fixed with new release v4.0
