Upgrading project from 4.6.2 to 5.2.1p2, major artifacts with uGUI elements

Sometimes empty Text objects display the font atlas

Sometimes there’s major artifacts and the elements don’t clear on the next frame so they get stuck on screen.

How some of those things are supposed to look: http://upload.dfyb.net/uploaded/NoDecay.webm

Any ideas?

Oh, it might just be this bug [5.2.1p1] Problem with Filled Sprites - Unity Engine - Unity Discussions

Will update Unity to see if it fixes it

yep, that was it
