That's exactly what we expect and ask for.  Just remember to have the
bug address on the CC line, so that this whole discussion is recorded
by our bug tracker.

Double buffering was added in Emacs 26, and the way to disable it is
explained in NEWS of that version (NEWS.26 if you have the Emacs 27.1
sources):

  ** Emacs now uses double buffering to reduce flicker when editing and
  resizing graphical Emacs frames on the X Window System.  This support
  requires the DOUBLE-BUFFER extension, which major X servers have
  supported for many years.  If your system has this extension, but an
  Emacs built with double buffering misbehaves on some displays you use,
  you can disable the feature by adding

    '(inhibit-double-buffering . t)

  to default-frame-alist.  Or inject this parameter into the selected
  frame by evaluating this form:

    (modify-frame-parameters nil '((inhibit-double-buffering . t)))

Please try this.
