Is this with or without double-buffering? If without, then it is not related to double-buffering, and should be reported separately. AFAIU, the display code used when double-buffering is disabled was not changed in any way that would explain these phenomena. If you have older Emacs binaries, I suggest to compare what they do on the same system with what Emacs 29.1 does when double-buffering is disabled. > > We had enough user experience before we decided to > > have this on by default. > > OK, good.

Even if you cannot show a reproducible "emacs -Q" recipe, it might help to see a clear step by step recipe with your configuration, which does reproduce the problem for you.
