Strange Facebook behavior

After one of the recent updates I’m getting odd happenings with Facebook. Whenever I try to comment or answer a post as soon as I type the first letter the screen scrolls down several inches and I can’t see what I’m typing and I have to scroll up to see what I typed. Also if I hit backspace or delete the entire message is lost and I have to start over. This also happens if I do an insert or backspace to edit. Doesn’t do any of this with other browsers. Not a laptop, it’s a desktop with a mouse, so no trackpad.

I9-9900K, 32gb, GTX 2080ti running a 43" 4K monitor.

Yes, I’m having the same issue with using the backspace and the screen scrolls. Is there a fix yet? I’m on a laptop with a mouse, no trackpad.
