25.1.50; After losing focus, cursor is hidden when moving point
Mon, 05 Sep 2016 21:16:40 +0200
I've tested this with a GTK build on GNU/Linux; other toolkits and OSes
might also be affected (but terminal mode doesn't seem to be affected).
emacs -Q -eval '(setq blink-cursor-delay 0.0)'
Move point around in the scratch buffer (e.g. press C-b a couple of
times): the cursor stays visible, as it should be. Then put the mouse
focus on a different GTK window (not Emacs window), put the mouse focus
back on Emacs, and move point again: the cursor is hidden, making it
impossible to see until you stop moving.

No further comments, so I pushed my last proposed patch to the
emacs-25 branch, and I'm marking this bug done.
