How do I fix the stretched title bars on maximized desktop apps

Huh? I don't see the results you are complaining about. It looks exactly the same to me regardless restored or maximized.

@PleaseFix:
I'd be interested to see some screenshots of your issue and what Windows theme you're using.

I have attached a picture of the issue.

The icons are exactly the same size in those pictures. They are not "stretched".

What you are seeing is something of an optical illusion. The title bar is slightly less "tall" by a few pixels when maximized, but the icons themselves are the same size.

Part of the issue is that what when a window is maximized, the "sizing handles" are positioned off screen, and in windows 10 the sizing handles are the same color as the title bar. This makes the titlebar seem slightly narrower (In windows 7 the titlebars were a different color, so it wasn't such an optical illusion.

The titlebar area is definitely 1 or 2 pixels shorter though. Also, it seems as if the left hand icon and text is further to the left when maximized, but again that's because the sizing handles are off screen, making the window appear more narrow.

@Mystere
That is what I am trying to fix.
