I have chilipeppr and the serial port server running on a raspberry pi 3. Raspbian boots directly to chromium in kiosk mode pretty quickly, and even the default TinyG workspace runs acceptably at 1080p. My goal over the next few weeks is to build out a workspace optimized for the pi3 performance limitations. I will need to make a few component changes also, it seems as though the shadow in the 3D view is problematic, and a few items can be tweaked for better touch input.
The WebGL on Raspi3 is a bit rough and flickery, but it looks like it’s working.
Yeah… Im working on that component right now actually
wait…what memory settings for the pi?
I have the memory split at 256 right now. Ive figured out whats going on. Finalizing my code changes now 
Just turned off AA and the issues go away completely. Must be a combo memory GPU utilization issue
AA?

Well, maybe just add a pulldown menu item for 3D viewer that let’s you turn it off. Make it a sticky setting so on reload it goes back to what was previously saved.
