Describe the bug
OS become extremely slow. window dragging. resizing. Basic functions slow down.
Disable or close BTT - and it's back to smooth OS sailing.
I just did a clean OS reinstall because I thought it was time after a year deep. but it is definitely BTT. And I cannot live without BTT!!!
Sorry, I know this was nearly 4 years ago but thank you so much for figuring this out. It was driving me bonkers and I do not want to live without BTT. Turns out it was my Logitech G900 set to 1,000 in G Hub.
Sometimes it seems like everything terrible that's ever happened is because of G Hub.
