I just created a fix for the Take Slack → Play Button → Red Light issue that I was able to replicate, but it won’t fix the issue in your case where the calibration values seem off.
I’ve been digging into it and I haven’t found anything wrong there.
The only thing that I can think is that somehow the calibration process is producing funky results?
Can you try running calibration back to back twice and see if we get the same coordinates each time? If we’re not getting the same answer every time that would be a good indicator that it’s something in the calibration process.
If we get the same (or similar) coordinates every time then the issue has to be elsewhere (or is more likely to be elsewhere I think)
