Graphical glitches when using GTK+3 on MacOS
Suddenly some gtk-based applications start to show some graphical issues in MacOS. Some dialog windows extend the width of title headers more than the window's body; besides, they show a flawed line at the bottom of it.
Another issue observed is that some menu boxes show the bottom line of the box-container cut.
Attached some screenshots of the issues corresponding to Glade designer (3.40.0) and gtk3-demo applications.
Specifications: - MacOS: Monterey/Ventura - GTK+3: Installed by Homebrew - Hard: MacBook Pro (Apple M1 Pro) / Mac Mini (Apple M1)
