Every few days when booting my Pocket Reform RK3588 it starts with only the upper half of the screen visible. It happens on battery and with the power supply connected. After reboot -sometimes twice- the reform comes back to normal operation. The view on an external display works as expected.
Is this a known problem? Is there a solution to solve this?

The problem is known:
It needs somebody to fix the panel driver.
Are you updated to the newest system controller firmware and kernel? I am wondering if you are still having this issue.
@wakest My kernel is up to date and I have the latest fw installed (20260227). I haven’t seen that behavior for some weeks since that fw update (…didn’t know that the new fw might solve that issue).
I’ll give feedback if it should ever occure again. 
great to hear! crossing my fingers this has been solved. def let us know if you see this happening again!
@wakest Unfortunately today it happend again. It occured when rebooting after an apt full-upgrade - don’t know if that was the cause…
