Thanks for the report.

While we are waiting for the double-buffering issues to be looked at,
you should be able to work around this problem by using the following
snippet from NEWS:

  If your system has [the XDBE] 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)))
