Astropad Studio - V3.4.0 issues

Updated to latest version. Updated luna firmware. Now, it slows down my macbook pro to an unusable state. It makes everything super laggy & my computer fans run at max while the ipad is set as an external display. If I close the macbook pro, and just use the ipad (only while connected via usb), it’s better, but if I open the laptop back up, it’s right back to being slow & excessive use of resources. I’m using the latest version of OSX on a macbook pro touchbar with iPad Pro 12.9. Any suggestions?

Astropad Studio has always been a resource hog. I bought a huge external monitor so I could keep my MacBook Pro clam-shelled, but it still runs the fan big time.
