Tried another test. In the monitor settings menu under Display there is a option called "DP 1.2", by default it is set to Enabled. If I set it to Disabled I get the PIP behaviour - Ubuntu detects the correct native resolution and the image appears.

If I set it back to Enabled the bug comes back.

Is their a bug in the DisplayPort 1.2 implementation that doesn't affect earlier revision modes?
