It’s only obvious in some waveforms/screens. But it’s there. It is not right below the plastic screen protector but underneath the plastic covering the display. It can also been seen when the unit is off. Pretty disappointed although I could’ve received worse.
What to do? Its not preventing anything apart form it bing really annoying now that I know it’s there. It’s like a dead pixel. You might not see it for years but once you know you got one, it’s all you can see.
The only way to sort this is to take the unit apart and then take the screen assembly apart and get the dirt out and then put it back together without catching new dirt or dust. I don’t have a semi sterile assembly room here. And neither does Elektron 
(Yes I know this is nit picking, but I expect a lot from Elektron, which is partly their own fault for making great machines.)
Think they came from an old cushioned box I pulled from the garage and used as an OT desk for a while. Haven’t seen em move in a while
