Client-side window decoration rendering glitch

[Luis Capriles]

When the windows of the aforesaid applications loose focus, a pixel wide line of the same color as the style (light/dark) appear at the top of the window title bar. While using Xorg/X11, the glitch doesn't occur.

Hi!
Just in case, the glitch can be seen when off focus in: Nautilus(files 42.6), System Monitor(42.0), Help (yelp), Characters(41.0), Web 42.4(Epiphany), Logs(42.0), Image Viewer(42.0), Calculator(41.1), Calendar(41.2), Disk Usage Analyzer(41.0).

For Terminal(3.44.0) and Text Editor(gedit 41.0), there is no glitch.

On non Gnome apps (e.g.: LibreOffice), is not observed.

Regards
