This happens to me often and I have not figured out a solution either. I will open a google sheet, and sometimes it will just not respond to my mouse or keyboard visually. But if I go to a different tab of any sort, and then click back, the previous input from my mouse or keyboard will be applied to the sheet. Yet any current mouse or keyboard input will not register again. But I can go to a different tab again, and again, any input will show up.
Compatability mode sometimes fixes it, but sometimes it's already on and it still does it.
Sometimes, they load like normal. I never know what's gonna happen.
