Also, the shadow overdraw bug is an OLD bug in Unity that has been around for quite some time. It was just harder to reproduce until 5.8. The shadow overdraw bug in unity was previously observed in bug 763579, and other bugs I can't find right now. I do have an experimental patch (never committed) which would allow me to reproduce similar Unity rendering bugs reliably.

I think it's all related to incorrect damage/rendering calls in unityshell. However I don't yet know enough to explain how yet.

Everyone -
If you can reproduce the flickering/corruption reliably, please try this workaround:
1. Run: ccsm
2. In Workarounds, enable "Force full screen redraw (buffer swap) on repaint".
