Did an issue ever get created for this? I couldn’t find one that corresponds.
I’m having an issue very similar to this with a screen that I have recently installed, it’s a 7" DSI capacitive touch. The touch seems to be available corner to corner, however some of the areas that you press are offset from the controls on screen.
I can run the calibration but the first crosshair just stays red when pressed and doesn’t progress to the next one. It also pauses the countdown timer.
It’s this one: https://www.waveshare.com/wiki/7inch_DSI_LCD_(C)
