Thanks Martin.

Your fix looks a little bit like mine; but I'm not quite sure what it
is doing; could you comment on what your patch does?  Mine was on the
AbiSource bug 13791, was taken by Debian and Ubuntu, and can be found
with detailed explanation at


But it didn't work well with Wayland, according to Hubert.  I'm not
targeting Wayland, so it was out of my scope.  When Wayland or a
compositor are used, the redraws would often have no visible effect.

I'd like to understand your fix as compared to mine.

You might also ask for feedback from Abiword users on 13791.


The quickest way to reproduce Write flickering at the moment is to
download Sugar on a Stick, for Fedora 28, which has the bug.
