Linux 32 and 64 bit - Random black squares in scenes

Title: Linux 32 and 64 bit - Random black squares in scenes
Reproduction Rate: Low
Blocker? No, unless you count ability to see a scene
Details: Black squares pop-up and can grow or shink in size as the camera is moved in a scene. I could not determine what in this specific scene was causing it. These happen on the overworld map as well.
Steps to Reproduce: Walk/run while using the 64 bit client and eventually you'll see this effect.
User Specs:
OS: Linux 4.4 Ubuntu 16.04 64bit
CPU: AMD Athlon(tm) II X2 255 Processor (2) System RAM: 12015
GPU: GeForce GTX 970/PCIe/SSE2 GPU RAM: 1024

Loc: Various

Here's another one. I caught it in the screenshot as small - with the tinyest movement of the camera it was also taking up over 60% of the screen as well. I tend to think this is a rendering issue and may be related to the issue that is being observed with the broken guard skins.

A couple others I didn't realize I caught when doing screenshots:
These two are right by Rift's End - notice how there is almost no mouse movement and yet black square, then gone. If I was as cool as @Chris I'd make an animated gif.



Here at entry to Vauban Pass, almost same exact mouse position as earlier screenie:

 

Thank you for reporting. This is a known issue.

 

I was wanting to make sure it is known to be a 64 and 32 bit bug, so unlikely related to the 32 bit libraries when running the 64 bit client issues. I also think it is likely related to the guard skin issue.
Hopefully Unity will provide some help soon.
