Hey
it's taken me all day but I put together a project that reproduces the issue.
I'm concerned that this might be GPU-related so I'm not sure what results you'll be getting from your machine. I've run it on two laptops with different chipsets and the tearing effect appears in both cases under the same circumstances.
it also appears on my iPhone 5s and my iPad 3.
Here's how to repro:
-load the project in unity.
-load the scene.
-make sure the game view is set to 1024x768 and that the game window is big enough so that it doesn't get scaled down (!!!)
-run the project (in the editor).
-press and hold right arrow for about 2 seconds (this moves the camera to the right).
-tearing should appear just for one frame and then disappear. you can use left and right arrows to hone on the exact position where it's visible.
if the tearing doesn't appear, you'll just have to keep moving the camera with the left and right arrow (hold left shift to go faster) until the tearing pops up. this can take a while though.
here's a weird thing, if I'm moving around with the arrows and I find a position where the tearing appears, the tearing doesn't actually appear if you copy and paste the same position into the transform component.
that's all I can do from my side, please fix this or provide a workaround, I can't ship a game with strange artifacts on it
