Pen issues

[Roethenbach]

Hello, I recognized a strange behavior of my pen on the SP7 when using iptsd. In the upper half of the screen the position of the pen is not detected very clean. Fast drawn arcs are looking very angular. In the lower part of the screen everything is working well. I'm using the surface pen and OS is Ubuntu 22.04.

Thanks

Sorry for the late response.

If you're still using this fork, you can try lowering the IPTS_DFT_POSITION_MIN_AMP and IPTS_DFT_POSITION_MIN_MAG values in src/ipts/dft.cpp.

With the official iptsd, you can set these options by creating /etc/ipts.conf and adding a [DFT] section with PositionMinAmp=... and PositionMinMag=....
