Replacing highlighted text creates a backwards jumble of letters
I started noticing about a month ago (may have coincided with an OS update but I can't be sure) that when I highlight text and then type new text (in order to replace the highlighted text), I get strange behavior. The new text I'm typing ends up in a jumbled order with the letters of my new words in reverse order from how I've typed them. Or also sometimes more words than just the ones I've highlighted get replaced. This is only an issue when I select text to highlight by clicking & dragging, NOT when I simply highlight one word by double-clicking, and also NOT when I take the extra step to delete the highlighted text before typing my new text. And then often when I command-z to undo the jumbled mess of letters, the cursor then moves itself to a random new spot in the text. This makes typing emails (or obviously anything) extremely aggravating, because making fixes to my already typed text now requires highlighting, then deleting, then typing my new text.
I've restarted in safe mode (issue persists) and also reinstalled OS ventura (issue persists). I'm at the apple store genius bar and after running diagnostics the tech guy here says I don't have a hardware issue with my trackpad. He's suggesting it's an issue with the fact that I'm in a non-native to apple environment (running gmail on chrome) and that it could just be a bug in the chrome or gmail software. I've googled the issue and can't seem to find anyone else having the same problem. I'm also having the issue right now in this discussions.apple.com forum while typing up this very body of text--in other words it's not an issue with how my system interacts with gmail software. Just tested and I get the same issue when typing emails on gmail.com via safari.
Anybody else encountering the same or similar issues?? I'd even be happy with a workaround fix for now, like switching to a different browser (but obviously I tried that and it's not working). Arghhhhhh. Any insight or commiseration greatly welcomed :)
