macOS: Fix rendering getting stuck on some machines after sleep/screensaver
This is caused, as far as I can tell, by CVDisplayLink getting stuck.
Apple apparently are incapable of writing a simple timer robustly.
So if it remains stuck after a second delete and recreate it to force it
to restart.

Fixes #2016
