Sadly not.  Starting a new emacs instance with the following did not
not have any apparent effect on the issue.

(custom-set-variables
 '(tooltip-frame-parameters
   (quote
    ((name . "tooltip")
     (internal-border-width . 2)
     (border-width . 1)
     (no-special-glyphs . t)
     (inhibit-double-buffering . t)))))

I also tried (set-frame-parameter nil 'inhibit-double-buffering t)
in the main frame, just in case that had an effect, but it did not.
