Set-up a new 3.5in display today and always ended up with a cursor in the upper right corner only when trying to boot to GUI, desktop will not be shown. DUT is a Pi5 running 6.12.21 kernelChecked the display when booting to CLI -> all fine (see pictures) Tested another (known working) display -> same problem: showing cursor only as well.
Any idea what is causing this? Seen such effect when MESA wasn't having mipi-dbi-spi enabled (if memory serves me right). Configured the DUT for labwc -> no changes made
when removing below parameters from the overlay the cursor will no longer be shown and screen is all black
Code:
