Yes, its still the same problem. Even booting without HDMI monitor gives
the same result. Another user get the panel correctly. Can I remove some
config files to fix this?

I tried removing .local/share/kscreen and restart the machine. Is there
any other file I can try and remove? Now the panel has moved to laptop
screen once I connect the HDMI monitor (I made Laptop screen as primary
in system settings). But if I remove the HDMI cable, the panel vanishes.

Lets hope that fixes it.

> Happy hacking,
