Comment (by quozl):

 Continues to be a problem in AbiWord, and by consequence also Write.

 Theme change workaround in OLPC OS is working reasonably well, though the
 activity toolbar has acquired the theme change as well on Ubuntu 16.04
 with updates.  Workaround does not work on Ubuntu 17.04 with updates; the
 flickering is back.

 AbiWord upstream hasn't found a fix yet.  Debian package is affected, but
 is orphaned.  Ubuntu package is derived from the Debian package.  Fedora
 package also affected.

 Various bug references:
  * https://bugzilla.abisource.com/show_bug.cgi?id=13791 (AbiWord upstream)
  * https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=851052 (Debian,
 AbiWord)
  * https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=848838 (Debian, Sugar
 Write Activity)
  * https://bugs.launchpad.net/ubuntu/+source/abiword/+bug/1574278 (Ubuntu)
  * https://bugzilla.redhat.com/show_bug.cgi?id=1287835 (Fedora)

 The problem depends on graphics performance relative to CPU performance,
 some people are unable to reproduce it, although instrumenting the draw
 callback described above can help to verify it is present.

 Options for Sugar Labs are:
  * find and fix the problem in AbiWord,
  * switch from using AbiWord to another embeddable word processor,
  * switch to a GTK+ rich text editor widget,
  * switch to GOffice or WebKit2 editor, if they are stable enough.
  * switch to a web activity.
