I believe I've figured out what was going on. It had nothing to do with the
white setting to #e5e5e5, but the fact that somehow in my .emacs file the
custom-set-faces contained the line:

 '(default ((t (:inherit nil :stipple nil :background "white" :foreground
"black" :inverse-video nil :box nil :strike-through nil :overline nil
:underline nil :slant normal :weight normal :height 115 :width normal
:foundry "unknown" :family "DejaVu Sans Mono"))))

I'm not sure how this got there, but removing the :background "white" from
it changes the window's background from dark grey to bright white again.
Text is now readable.
