I managed to work around the problem. In my xorg.conf file were
present the following resolutions:
"1680x1050" "1600x1200" "1400x1050" and so on. I removed the
"1600x1200" and now everything is displayed properly. The clue was
when the xorg log file stated that my virtual screen size was
1680x1200 and the only "1200" I could find was in this spot. Anyway,
all is good now though there appears to be a bug somewhere in xorg.

Yet another update. I manually set the display size (according to the
xorg wiki multiplying the resolution by the dot pitch) which did not
help. And then I looked at the log and saw this ominous looking line:
Virtual Screen Size determined to be 1680x1200
It should be 1680x1050. Why is the virtual screen being set to a size
larger than the actual resolution?
