You need to quantify your observations here. When polling is enabled, then
every 10s the worker will be awoken and consume CPU time checking that all the
displays are the same as before. Unless on your machine it takes a ridiculous
amount of CPU time (say greater than 5%), it is just the cost of the ability
for your computer to automatically detect display changes.

The real bug is the latency it induces... But I digress.
