That was it! Many thanks!

The Acer has the same problem. The Live CD likewise has the problem.

and i'm a complete dumbass. this whole time i have meant left....not right and i never noticed my mistake. many apologies gentlemen!

There's no data dumping to the journal when I click. I have an older Acer laptop with totally different hardware that i'm going to test on. See if maybe it's a Dell touchpad issue or something.

I first noticed it on the older ISO but I only grabbed that ISO two days before the most recent one so I didn't say anything as I wanted to test the new ISO first. All 3 machines right now are on the latest ISO.

Chrome or Firefox. It doesn't matter. I can duplicate it with two Dolphin windows even. Single monitor on different laptop models. Dell E7270, E7470, and Precision 5510. So multiple resolutions from 1368x768 up to 1920x1080.

Maybe I don't understand this properly. I open chrome, make it full screen. I open dolphin in front (anywhere on the screen). I then move the mouse as far right as it will go and then left click (and for me it focuses chrome as expected)
