Comment:

 I've fixed it in AbiWord and made a custom build.

 The problem was in AbiWord; the caret cursor blinked more than it should,
 calling `Gtk.Widget.queue_draw()` on each blink, passing the whole drawing
 area, thus causing many `Gtk.Widget.draw` events.

 Most critical change was to call `Gdk.flush()` instead of
 `Gtk.Widget.queue_draw()`.

 The problem was difficult to reproduce for some people because it was
 caused by a race between a 10ms timer and the event queue.

 So I'll close this now as ''notsugar''.
