This has been happening from time to time recently: I visit a file
(either through recents or through project-find-file), and the buffer
stays blank for a while, giving an appearance that it's "loading".
But if I issue a new command (e.g. move the cursor), it redisplays
instantly.
This happens with my personal configuration, and rather randomly. How
should I go about debugging it?

Are you sure this is because redisplay is not happening, and not because
Emacs is stuck in xg_select?
If you hover over a tool bar button when this happens, or move the
mouse, does the button become highlighted or redisplay happen?
