"Ghosting" Effect on Dell Precision 5520

I think I have found cause: The integrated panel could be the problem. I have now also tested it with Ubuntu 22.04 and it still has the “effect”. But when I connect an external monitor everything is normal as always.

I think I need to change the panel to see if it fixes it.

Update: i tested on a new 5540 and got the same with the integrated display
it would be weird if both panel would be broken.

strange that the external monitor has absolute no issue at all, only internal one
