RX570 weird glitch?

I have a RX570 card, which I recently added to an oldish i5 3570k build.

I have noticed some strange graphical effects which don't look right. I haven't changed any default settings and I'm running at 1080p. Can you see from the s/s that there is a kind of snow.

The snow is more visible at full resolution.

What's the issue here, am I seeing things or is my card defective?
 
Have to be honest, I can't see anything wrong...? Even with your large screenshot all I can see is the GUI and a completely black background. Check your video cable in the first instance perhaps?
 
Agreed with others. Looked at the screenshots and in full res, and all I see, is what I expect from the screen. No snowing of any kind. Which like the others have also said, suggests GPU, Cable (DP/HDMI/DVI) or Monitor. With the easiest test being a simple switch of the cables first. GPU because you have the 3570k I believe has internal GPU, so you could test on the motherboard HDMI/DVI port with the cable. And if both of those fail, it's most likely the Monitor then.
 
I am using HDMI and I have tried swapping out the cable but the issue is still present.

I'll try a different monitor next.

I tried CS:GO and that looks fine, which is confusing.

So you've tried the Monitor and Cable swap. So really what you need to do is try out the onboard DVI/HDMI/DP and see if that has the same issue. That will tell you whether it's the GPU or whether it is something else.
 
Hmmm, just thought of another possible result and solution since the card is new.

Go into the AMD Drivers, and check the signal (Pixel Format, for Displayers) is using the proper one for your display: eg RGB 4:4:4 PC Standard (Full RGB).

I had a monitor that kept causing the GPU to switch to one of the YCbCr's even with HDMI connections. Something about how the HDMI on the monitor was implemented causing funkiness to the HDMI signal to happen. It might impact on what you're seeing, so check that out too.
