Configiration: Raspi 2 B v1.1 with Display v1.1 (2015), latest RaspiOS (2022-09-22 Bullseye 32bit), no modifications in settings made.
Setup worked with an old NOOBS (1.9 or 2.4) for some years until the SD broke.
With current RaspOS, touch input only works in the upper left area of the screen (about 700x100px). Using an external mouse, everything is fine.
I tried xinput_calibrator but failed (mouse cursor cannot moved to the lower two bullseyes).
