Workaround forces screen capture to fix MacBook cursor lag

Category: Apple
Status: discussion
Sources: gist, discussion
Summary: A widely shared gist (211 points) documents a workaround for cursor lag on recent MacBooks that periodically records a single pixel of the screen every ten seconds, apparently keeping a display or power path active enough to avoid the stutter. It is a practitioner hack, not an Apple-confirmed fix or diagnosis.
Why it matters: It points to an unresolved input-latency or power-management regression on current macOS hardware that Apple has not publicly addressed.
Follow-up: Watch for an Apple acknowledgment or a root-cause diagnosis.
