[SP4] Pen Stops Recognising Contact

[AngelTomkins]

Surface Pro 4
Arch Linux, package: linux-surface/iptsd 3-1
Kernel linux-surface/linux-surface 6.11.4.arch1-1

Problem:
On system startup everything works well, after some time using the pen in xournal++, the pen input doesn't allow lines and a bunch of dots draw instead of a line. Then later the pen does not appear when hovering over the screen. It appears in the correct position when the pen nib contacts the screen, but nothing draws.
Seemingly the error Tried to read 12 bytes with only 4 bytes available! was only being outputted when I attempted to write with the pen and the dots appeared. After the pen stopped appearing from hovering the errors stopped continuing.

Restarting the service seems to have undefined behavior where, sometimes it fixes it, other times it keeps having the dots instead of lines drawn. When the dots were there, there was more of the error Tried to read 12 bytes with only 4 bytes available!

I have the same thing, only it's 7 bytes with only 4 available. Can't seem to fix it...
