S-Pen issues
I also have the same issue of palm rejection not working, which also seems to be an unfixed issue with the LOS 16 ROM also.
It's not specifically that it doesn't actually draw, but rather that any fast writing is being lost. I don't know if this is due to the new wac_i2c->enabled_gestures introduced in commit 05fb0bf8174c. If it is, I see no way to disable the gestures inside the ROM.
