Hidden mouse on Final Cut Pro

Finally someone running into my problem and recently too!. I just got the new MacBook M1Pro few months back and first time using Final Cut. After few uses I noticed the mouse "disappears" while I'm editing. Later I noticed that the mouse was actually moved to the lower left and stayed there (I can see my mouse is forced there despite my attempts to move it). This only happens when Final Cut is running.

I want you to imagine how frustrating this is, you are editing and all of a sudden the mouse snaps to to bottom left and stays there and you can't continue your editing, it stays there for a good 5-10 seconds until it is released.

I tried the delete preferences option but that didn't help. Any help is appreciated. EtreCheck reports attached.

Adding that final cut came with my MacBook Pro already installed.

Start by deleting preferences.

To delete preferences, hold down command and option while starting FCP X and click Delete Preferences. The application will start in a default state, and open an “Untitled” library.

Reopen the library you were working on, set the preferences the way you like them, and try again.

If the problem persists please run Etrecheck and post its full report here.

Never heard this one before but whenever weird things happen it's a good time to try deleting the preferences.

As you launch Final Cut hold down the Option and Command keys and in the window that opens click on the "Delete Preferences" button.

Please tell us what version of FCP.

Not sure if any of that has an impact on the mouse issue, but you certainly have things in that report that need to be addressed.

You have Chrome, and that wreaks havoc on video applications like Final Cut Pro.

See https://www.chromeisbad.com for why, and how to remove the bad keystone daemons.

This one I had not seen before:

I have been using Final cut for 2 hours now and I have never seen the problem again! All I did is what you suggested to delete chrome and all its dependencies. I don't even use chrome I just installed it once to test something.

Thank you so much and I am on the latest Final Cut 10.6.2 and I already notice significant performance difference.

Hopefully the problem doesn't come back if it did I'll update the thread. I don't think it will because I used to get it every few minutes and since I removed Chrome I have been heavily editing for 2 hours and I don't see it.

Thanks again!

I can confirm after an entire day of editing I never got the mouse snapping and freezing behavior, not even once during that time.

Seems like Chrome was the problem.
