Thanks,
I've verified graphics emulation is set to 2.0, even tried changing it's values..
Another note, Example 9 also affected the same way and text becomes unreadable. So far only way to restore closing & reopening unity.
And a final note.. I can go between all the example scenes without a problem unless I open examples 5 & 6. As soon as I open those and go back to 7 or 9 display is corrupted...
So I assume, those scenes are setting something and it stays that way?
That's on Windows btw...
