Graphical artifacts near the window border when the window is resized
It's hard for me to guess why this happens, but this effect appears regardless of the compositor (xfwm4, compiz, picom...). GTK3 CSD windows are slightly less affected by this and so are Qt applications.
Maybe it's not even caused by the window manager, but by the GTK, I don't know.
