Ever since this issue happened (and yes, I understand that correlation isn't causeation, I'm just pinpointing when the issue began for me) I have been having a odd graphical glitch while I am in station. If you don't mind watching this video it shows it better than I can explain it. If VO was a horror movie I would be expecting a jump scare right about now.

Just watch the background and you can see it. It's been a regular occurrence and not just at one station. With and without plugins installed.

Using DX11 Driver

Just off the top of my head, that looks kind of like a driver bug. I've seen similar things in the past, that proved to be driver problems.

AMD has been pushing out a ton of new drivers, lately, because of all the VR stuff. Perhaps try updating to the very latest and see if that helps?

Inc, I originally thought the same thing, and didn't bother to report it since I use Mesa from git. But... now there's someone reporting the exact same thing on a totally different OS, with a totally different driver, and a totally different GPU architecture.

I get visual glitches that look identical to those in this video.

AMD Phenom II X6 1100T
AMD Radeon HD6870
Mesa (git from about a month ago, i cant check versions. PC's in storage.)
Linux 4.2, i think.

Isn't it a common codebase, though? Didn't AMD contribute a bunch of their stuff to Mesa?

I have an R295x2 at home, and the latest drivers (albeit Windows 7), and I haven't personally been seeing this. But I'll keep an eye out.

At work I currently have this Steambox thing running Windows 10, with an Intel Iris HD or something, and it has some totally different freakshow flickery problems on occasion, but they're much more texture-driven.

I definitely can't rule out the possibility of it being the game. But we've never seen this on NVIDIA.

I guess you could try disabling threaded rendering, and see if that helps? I'm not sure what else to suggest, beyond that and driver updates. Debugging this kind of sporadic issue is a nightmare.

Common codebase (amdgpu) on Linux didn't start until the most recent generation of GPU's. The 6870 is their old vliw architecture.

I'll test turning off multithreading, but that may have to wait a month... or two.

Ah I believe that is the background glitch bug I discovered over the weekend and fixed in the windows version now.
The next Linux update will include the fix as well.

Disabling threaded rendering will also fix it.
