It sure sounds like a bug in the GNOME compositor now. Have you tried disabling GNOME Shell extensions one by one? Maybe one of them is responsible for this.Whether or not we find some workarounds, I think we should add an entry to PROBLEMS about this.
Speaking of disabling double buffering as a workaround: I went back to my old bug reports related to flickering, which double-buffering aimed to fix.
I recompiled the GTK3 build without xdbe -- and still couldn't reproduce neither bug#12363 (which was admittedly filed on a Windows system), nor bug#16621. Even with the same font (Fira Code).
Not sure what changed -- maybe better screen resolution, or a faster machine. And the DE, libraries' versions, etc.
But there is a persistent glitch: when the window configuration changes, 1 or 2 vertical bars often flash:
https://a.uguu.se/iYTlOftH.mp4 (with emacs -Q)https://a.uguu.se/YdDWpMid.mp4 (with my config but with tool-bar and scroll-bar modes enabled)
scroll-bar-mode on seems to be required to reproduce this.
