I just installed a Dell Latitude E5270 laptop and noticed that the builtin
screen flickers sporadically��� for a fraction of a second on both, text console
and X.

It looks a bit like a lose monitor cable, but I can exclude a hardware problem,
because it also happens when I don't even touch the device, but it does not
happen under Windows 10 that came preinstalled on the device.

I discussed this with Stefan Dirsch and he suspected a bug in KMS.

Please let me know what other information you need for tracking this down.
