I recently upgraded my aging 6870 to an Rx 480, and got everything booting with the AMDGPU open source driver.
From time to time I experience what looks either like a super low colour version of everything, or a negative (white is black) that persists through reboot.
I had the same issue with the 6870 on the xf86-video-ati open source driver, but it resolved by installing the catalyst drivers. Is this an issue anyone else has run into and might know the solution to?

If you can manage, catalyst installed from vi0l0's repository by following the arch wiki correctly is a blessing and a half. At least on my end. Everything from games to screen brightness to auto connecting second monitors (im on a laptop) just simply does work that much better with catalyst. I highly recommend it. Especially if its known to fix your issue. I could never manage to use the open source drivers for my AMD stuff which I think is a very sad thing . Otherwise, if you wish you use the open source drivers (and good for you if thats what you want!) I cannot help further.
I am diagnosed with bipolar disorder. As it turns out, what I thought was my greatest weakness is now my greatest strength.
Everyday, I make a conscious choice to overcome my challenges and my problems. It's not easy, but its better than the alternative...

That would be too easy As mentioned, I'm now running the Rx 480, so catalyst is a no go.

AFAIK the RX480 uses the new amdgpu kernel driver (with the open/closed userspace driver). Polaris support was added in 4.7 which isn't available in Arch atm...

I had to compile the linux-mainline kernel. Without 4.7 xorg will not start at all on the 480.
Regardless, I had this issue on the open source drivers on the 6870 before using catalyst on that card, which makes me think that this is not specific to this card, but an issue somewhere between the open source drivers (both xf86-video-amdgpu and xf86-video-ati) and something on my system, but I'm not sure what. Given that when I try to screenshot when the issue is present the resulting image file appears normal, I'm thinking it's a compositor related issue, but I have tried both the xfce default, compton, and even booted gnome on wayland with no difference.

Perchance it's not related to this reported firmware issue: https://bbs.archlinux.org/viewtopic.php?id=215626

I don't think so, as it's not so much corruption as it is almost like colour depth dropping out or inverting, then slowly coming back. I also experience no system hangs at all. Also, as mentioned this issue existed previously on an older card as well and is not unique to this card.

Ah, in that case I'd start by running some hardware tests / swapping bits out.

Hardware has all tested good and is stable in windows, and was stable without issue with catalyst on the old card. Ram passes multiples runs, no issues on stressing CPU etc. I might try to move the whole thing over to another box I have, but that potentially adds another set of variables.

It's strange that it persists over a reboot, and is similar on both cards. Suggests to me that you might have a dodgy cable or connection.

Well my face is officially red. Apparently somehow my mkinitcpio.conf had early kms setting radeon... explains why I was having the exact issue I was having with the open source radeon driver. Seems better now, touch wood.

Ah!
Glad you tracked it down
