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.
