At Wednesday I've received my exchanged Edge 1030 due to blue halo. First, I was very happy, it's readable again in bright sunlight agin.
But just two days later, strange and weird behavior started. Display turns white or blueish, sometimes you can see a distored view of the datascreen, but mirrored. It begins to happen when the edge is running over an hour. Sometimes, normal display is showed again, most of the tiimes it switches back to white/blueish.
I've made a few videos to show the issue:

It's reproduceable. When the issue occurs, I apply little pressure on the casing around the display and the issue is gone. When I release the pressure, a few seconds later it's starting again to happen.
It seems like a hardware issue, I think the edge has to get exchanged one again.
