I've been using an R9 Fury X for a few months without issue, but about a month ago, I started getting static-bars flashing across the screen in certain games, usually in games with unlocked framerates going above 60FPS. I've done a little testing of my own with two different monitors at different refresh rates, with different cables etc. Here's what I've found so far:
Games with locked 60FPS seem not to trigger it, so it may be an issue with games going above 60FPS. My monitors are both 144hz, 1440p Freesync monitors. Both are using the DisplayPort cables provided by the manufacturers, and I have tested with two other DisplayPort 1.2 cables and gotten the same results. I've also tested with all three DisplayPorts on the GPU, and gotten the same results.
This happens with Freesync on or off, but stops if I lock the monitors down to 60Hz. At any refresh rate above 60Hz, such as 100Hz, 120Hz etc, it happens. It also happens on the monitor the game is not running on
This happens on older Catalyst drivers as well as the most recent Crimson drivers, including the 16.1.1 Hotfix released on the 4th of February 2016.
AMD Overdrive is running on default settings, and I have not overclocked any component of the system at any point.
OS : Windows 10 Home 64-bit
GPU : XFX Radeon R9 Fury X 4096MB
CPU : i7-5820k @ 3.30GHz
Motherboard : Asus Intel Lga2011-V3 X99-A M.2X4 SATA
RAM : Corsair Vengeance 16GB (4x4GB) DDR4 PC4-24000C15 3000MHz

PSU : Corsair AX Series AX860 860W Platinum Power Supply
Monitors: BenQ XL2730Z on the right. Acer XG270HU on the left.
I recorded and uploaded a video showing the problem in action: Screen Artifacting - YouTube
Any help with this is greatly appreciated.
EDIT: So I found someone having near enough the same problem Fury X flickering lines in games when using displayport
The fix they used, a program called ClockBlocker, also works for me ClockBlocker (profiled AMD power-management control) - Guru3D.com Forums
So this is a driver issue based on AMD overdrive underclocking the GPU further than it should be for the load it's processing.
This is something that AMD should have fixed months ago.
