Heavy Magenta Artifacting in Highlights - Damaged Sensor?

[janm]

Problem occurred while shooting reflective car outdoors in bright sunlight. Not sure what setting ND was at.

Another example, indoor ceiling lights.

Problem persists after turning camera off. Changing ND or shutter speed changes shape of the magenta blob, but doesn't eliminate unless rest of scene is heavily underexposed.

Google searches pull up magenta color fringing, but nothing this extreme. Any ideas?

That's not color fringing, that's a bad sensor. Time to send it to Panasonic for repair.
