The title bar that has the buffer name in it (and thus has to be updated when a buffer is visited), is necessary to reproduce the problem. I just said that an unchanging title bar does not bar me from being able to note the lack of the problem (because I originally described the problem as a delay between the title bar update and the frame refresh). >>> If you manage to create a MRE without your full config, you could >>> file a bug report and point to that difference between fullscreen and >>> non-fullscreen behavior. >> >> My MRE uses '-Q', I've posted it here recently (23/02/2023, 18:46). >> > > I mean: an MRE to reproduce the multi-second delay, which makes the bug > apparent even without a title bar. The delay is multi-second only with my personal config, correct, but I haven't been able to reproduce the problem with unchanging title bar, or without a title bar. >> You said you couldn't reproduce it, though.

I see, thank you. For anybody else who might want to try with GNOME, though, my installed version is 43.1 (one that comes with the latest Ubuntu release).
