There seems to be a BIG problem with this card idling at 100% GPU usage even when not gaming. Users report that after streaming 1080p Youtube videos, the card will use 100% of the GPU and will run quite hot doing nothing. Perplexingly, the activity returns to idle only after logging out or rebooting the PC.

Temperatures idle neat 80C. Until the user is logged out or the computer rebooted.

I do not think there is a crypto miner running but it can't be 100% ruled out because AMD has done NOTHING to block miners at the driver level, even as an option. Would not surprise me if this wasn't some NSA crypto miner running that no one can detect yet.

Linking to other forums for proof.

It's been a known issue for months even if AMD can't be bothered to put it in their release notes, they prefer to silently waste your money (~40W on my undervolted R9 Fury crossfire setup)

Interesting, from those two links, especially AMD Kyle's answer in the first one, they are pretty much aware of the problem, so why aren't they acknowledging it in an official manner?

But more troubling to know is that the likely culprit for the problem, the dvr functionality, as mentioned by Kyle, is always running and there is no checkbox during the driver installation process to not have that component installed.

That is a major no go for me. Superfluous stuff like that should be optional. Not to mention that a function that can be recording screen output continuously may bring with it security problems, and as it seems, it's buggy as it is and is responsible for the high GPU usage.

I have a Gigabyte RX 480 , had it since release . It is on an AsRock B350 mobo with a R5 1600x , running Win 10 / Linux mint 18.3 Mate .
I am unable to reproduce the problem .
The pc mostly does Netflix and youtube and mostly runs on Linux .
I game on an Intel / Nvidia rig so have not tried much in the way of games . I did however run a few benchies and no issues .
Does this only occur when the RX 480 is on an intel platform ?

this happens to me.. i didnt know it was a known bug or just bad driver install or something with windows 10.. but i have 2 480s in crossfire and sometimes i hear the fan on the 2nd gpu running fast.. i check and its 100% in wattman.. only restart fixes it.

The easiest way to trigger the bug is to watch a few videos on Youtube with Firefox
That is what I was talking about , does not happen on mine . I have not had the issue at all .
