SUMMARY
Toggling greyscale/inverted role can cause SEIZURES

STEPS TO REPRODUCE
1. Assign invert colours or greyscale to a keyboard shortcut (in my case,
Ctrl+Ç and Ctrl+Ñ, respectively)
2. Press and hold one of the keyboard shortcuts

OBSERVED RESULT
The colour change happens only once, or at least does not flash 3 or more times
per second

EXPECTED RESULT
It flashes way more than that, which can cause seizures
