        <pre>Description:
Lately (not sure only lately), I have been seeing row numbers on the left be
black boxes.  If I force refresh, e.g. "Insert new row", all the ones below
that redraw correctly. Scrolling off and back on does not fix.

I see black boxes over the numbers / letters.  Should be black numbers on grey
background, but I was getting back boxes on grey background, completely
covering the number/letter.  Sometimes just 2 couple in a row, sometimes 50 in
a row.  But always contiguous.

Steps to Reproduce:
1. Open a spreadsheet
2. Scroll up and down a few times randomly
3. Some row numbers are blacked out

Actual Results:
It happened.  I even opened a smaller spreadsheet with only a small number of
used cells and it happened.  Actually, then I opened a new spreadsheet and
there were immediately blacked out row numbers AND column letters...
I also notice I only need to click on a cell (like N8) and then the N and the 8
redraw correctly.

Disabling OpenGL does not fix.  But it appeared there were less back boxes.
Causally related? Not sure.

Switched back and now I can no longer duplicate.  I was going to attach a
screen shot, but no longer can I guess.  

Expected Results:
Numbers / letters to show normally


Reproducible: Sometimes


User Profile Reset: Yes


OpenGL enabled: Yes
