This seems to occur more when the CPU is under stress. To repro use a CPU stress tool, I use CPUSTRES.EXE that can be found here -
https://blogs.msdn.microsoft.com/vijaysk/2012/10/26/tools-to-simulate-cpu-memory-disk-load/
Run it at high until you notice the CPU usage go up then in your game mouse over any 2D UI element and you will notice this issue occurs nearly every time.
Hope this helps diagnose the issue.

For me this only occurs on Android (GearVR) for some reason. All canvas items flicker in the right eye only when "mousing over" UI elements causing shadow effects to be enabled/disabled on text options. Whether the problem occurs seems to depend on the position of a scrollbar's fill image, presumably because it intersects with another element.

Having the exact same issue with Windows builds.
Happens in every scene especially if there is a text field selected. If I deselect the texfield it happens a lot less. With the text field selected it happens around 15/30 frames...
This needs to go to the TOP of the fix list!

Thanks for looking into this guys!
We are experiencing this on Android in GearVR with Unity 5.3.1p2. It can and does corrupt our entire UI, which is a huge part of our service. We have a repro where every single frame the entire UI is massively corrupted by reading the wrong textures.
We are attempting to update our app on the store this week. We are required to update our version of Unity when we do so because of Oculus's requirement that we move to the 1.0 version of their runtime.

Yes, please fix it ASAP - with no workaround, this is real showstopper

This issue should be fixed ASAP. It's impacting our project too. I can confirm that this happens in GearVR too

We're having this issue, and it manifest itself only on android and only with multithreaded rendering enabled.
Due to the nature and visual of the bug i'm inclined to think this is threading issue - something somewhere binding wrong textures sometimes.
Bug is not happening on static gui, but for example if you are to add/remove element to scrolllist (like you do in infinite scrolllist) it'll flicker.
