palm rejection artifacts
iptsd works fine for multitouch and stylus, however palm rejection is still not working well. It creates artifacts under mypaint and wobbly lines under krita. Here is an exemple under mypaint. I would love to help debugging this.

os : kubuntu groovy kernel : 5.9.1-surface iptsd : debian package and git master (c) version
I have the same issue with artifacts in OpenBoard.
My system: Linux Mint 20.04 kernel 5.9.3 iptsd 0.2.1
Same here, Surface Pro 5 with Arch Linux. Is there anything we can do to help? This is the one main reason why I still need to dual-boot Windows on this device.
Thank you!
Have you tried calibrating iptsd?
