When editing a long ODT document the display (sometimes) goes into
redraw-expose-redraw cycle which can take anything from a few redraws (~5
seconds) to several minutes (>30 redraws) to recover from. The UI does not
respond to any commands while flickering - clicks, arrow movement etc. are
handled only after the flickering has stopped.

The problem seems to be concentrated while navigating pages with tables.

Issue 51544 and issue 57984 seem to have a similar problem, but they do not
mention anything about tables so it might be a separate issue.

A few notes:

- During flickering the UI components themselves are not painted. If I switch to
another desktop and back, then all the non-document portions are colored gray
(by X through the window background) and are not drawn until flickering stops.

- During flickering only the document portion is drawn (white background).

- The document portion is only partially drawn before a new redraw cycle occurs,
e.g. the document goes like "blink - white document window - text draw starts -
continues and draws parts of the page - blink - repeat".

I took a video of the redraw flickering and put it at
http://www.iki.fi/santtu/oo20redrawflicker.avi but I am not sure whether I
should have included it as an attachment (its 800k after all). Please note that
on this particular case I first and fetched the camera, fumbled with settings,
took the video clip, and it still continued for about half a minute after
finishing the video clip.
