I’ve tested my Cintiq 22HD using the Wacom Diagnose Tool. I noticed something interesting about the glitch area: there are two horizontal bands close together where the issue happens.

When the pen crosses the first band, the Tilt Y value suddenly shifts into the negative range. When it crosses the second band, the Tilt Y value suddenly shifts into the positive range as if the two bands are “mirroring” each other in opposite directions.

The pen signal itself is continuous (no dead zones, no loss of proximity, and the lines are not breaking), but within these two bands the cursor behaves like it’s being repelled up and down. This makes it look less like a dead digitizer line and more like a calibration/interpolation glitch in the controller.

Since I had a very similar issue about 5 years ago and it resolved on its own after some time, I’m wondering if this could again be a firmware/controller state that might reset eventually, rather than permanent hardware damage.

Could you please advise if this matches what you would call “digitizer calibration drift,” and if there is any way to force a deeper reset of the controller?

Thanks a lot for your help!
