Michael Danzer suggested I try the "DisplayPriority" option.

Setting this to "BIOS" does not help.  Setting it to "HIGH" seems to
cut down on the frequency of all the display glitches I mentioned, but
in the past five minutes that the X server's been running, I have seen
all of them at least once.  (By comparison, they were pretty much
happening all the time with the default.)
