Pen Pressure issues

I'm working on my cintiq tablet, it is doing super weird stuff with pen pressure.  I have it hooked up to my laptop and another monitor.  Whenever I switch to click on someonthing another monitor, the pen pressure just goes away in Photoshop when I come back to my cintiq.  I have to unhook and rehook up the tablet to my laptop.  Then, it still isn't working right. See the attached screenshot. When I try to start painting or drawing using pressure sensitivity, it leaves a big blotchy mark that is the shape of the brush, then the pressure sensitivity works as it's supposed to.  This makes actually painting anything impossible.

 

I have installed the latest driver for wacom. I have installed photoshop updates.  I have installed the latest version of Mac. I have restarted the computer, several times.  I called Wacom and they walked me through trying to solve it and nothing worked, they told me it was a photoshop issue.  So I tried to contact Adobe and they told me I don't have a subscription and they won't help me unless I have one, even though I do in fact have one through my university! I have creative cloud installed and the latest version of photoshop.  I'm sort of at my wits end trying to figure this out, hopefully someone here knows what's up?
