Reflection Artifacts on Standard Shader

Question

UPDATE

I've been doing some experimentation to see if I could narrow it down some, and so far I've learned this has to do with HDR somehow. I placed a reflection probe in the scene and baked it with HDR. Came up exactly the same as the baked global reflection. Turning off HDR and it baked normally, no artifacts whatsoever. Any Unity developers got any clues about this?

So I've been using Unity without any major issues for a while now. But when I fired it up yesterday I noticed that something is up with the reflections. As shown in these images the artifact seems to be square mixes of red, green and blue, which to me alludes to a broken GPU.

Material Preview Standard Shader as seen in the Material Inspector

Scene geometry is showing the same issues of course

However, I'm not giving up hope and I'm posting this here in case someone knows what's up or maybe have some ideas on how to solve it.

Some things to note; I'm not running any graphics emulation, I'm running DX11 on DX10 (according to unity) and I've rebooted everything possible.

I am having the same issue. It started after I updated to Unity 5.5.1.f1 from 5.5.0 I believe.

My GPU is a GeForce 8400GS.

Here is a screenshot of one of my Terrains. You can see the artifacting appears to be happening in the cubemap. This does not happen on my other PC which has a GeForce 970 GTX.

Awesome! In the sense that I'm glad it's not a hardware issue; I'd hate to throw away my laptop. So where to take it from here? I'm gonna start a forum thread, see if I can get any devs attention to this issue

@bicyclol Did you make the forum thread? Could I have a link to it? Thanks!

@bicyclol @DevJHP I went and made a thread about it myself: https://forum.unity3d.com/threads/reflection-artifacts-on-standard-shader.456550/

With GeForce 9600 GT also occurs. (I owned also your GPU, and this happened)
