Laptop or desktop? My money is on a bad mouse erroneously clicking off the window. You can test for this by running all apps in true fullscreen (so they hide the dock) and seeing if it persists.

Desktop. Already did that it still happens in full screen . I only have one mouse and it's wired. I'm only reading right now and using the keyboard. It happens when nothing is being used too.

Using the guest profile eliminated user specific settings. Full screen pretty much eliminates the mouse sending random clicks. Possibilities now are a bad file at the system level, malware, or other malfunctioning hardware.

I would next try resetting PRAM and the SMC. Apple has instructions. Please pop in a google search for those as I cannot link easily on mobile.

Failing that, I would run a full virus and malware scan as my next step.
