Multi-touch screen with rpi not responding
Version
2.0.11
Hardware / Firmware

What happened
Running a raspberry pi 4b with Eviciv 7" multi-touch HDMI screen with usb for touch input. Rpi OS 32bit updated to whatever is current version as of today.
I know raspberry pi touchscreens are finicky to get multi-touch functioning, and the single touch does function, but I have not been able to get the visualizer to respond to multi-touch for zoom or pan. Some, not all, other programs, such as chromium, do recognize the multi-touch. When remote viewing my pi with VNC viewer, I am able to use my windows 10 touchscreen to pinch zoom correctly.
With all the clunkiness of pi OS interaction with multi-touch screens, I am unclear if this is really a bug or a conflict of some kind.
How to reproduce
From a raspberry pi 4b installation with the Eviciv 7" multi-touch screen, run UGS and try using 2 fingers to zoom within the Visualizer window.
Operating System
System: 32-bit Kernel version: 5.15 Debian version: 11 (bullseye)
Anything else
Problem is 100% of the time.
