⚠️ Borders in GTK3 application windows 🐞

[abraaorosa]

Could someone please help me remove these white borders that are showing up in the GTK3 windows? In other applications it does not appear only in these.
Please, I tried all the ways but I couldn't remove it.

I thank the attention 🙏

Hello guys. I managed to solve the problem by changing some expressions in the theme's GTK style sheet.

To resolve, go to:
./usr/share/themes/Windows-10-dark/gtk-3.20/gtk.css

And change values to:
.solid-csd decoration { margin: 1px; border-radius: 0px; background-color: #191919; box-shadow: none; }

You can see that the GTK3 windows have no white borders.

Thank you!
