eso weird bar

I noticed I was getting the same graphical error on RADV recently (within the last week or so) when playing both Warframe and Elder Scrolls online via DXVK. It's this weird bar that shows up on the left side. (see pictures).

At first I figured maybe it was a DXVK bug, so we checked logs with no errors or anything odd. Then I checked different LLVM versions (tried 5.0.0,5.0.1,6.0.0, master) and still the bug persisted. Finally I had two friends, one on mesa 17.3.7 and another on mesa 18 rc5 who didnt have the issue. So I tried mesa 18 rc5 and sure enough I didn't have the problem. So I went back about a week in commits on mesa-git, and sure enough, the problem was gone. 

So I then did a bisect, and after a few more hours, I found commit
f7ffa504a065dc2631fd38cc5fe885b277f4e7e7 to be the cause.

Once I reverted this commit and the two following commits related to it, the error was resolved:

  git revert --no-commit a8d55374dc4be7eaeac4684d259c1ef56a4dc30a
  git revert --no-commit cf0a95afacc24f79a22c9b00b29a27061fe195a0
  git revert --no-commit f7ffa504a065dc2631fd38cc5fe885b277f4e7e7

for clarification I am currently on an RX Vega 64, llvm 6.0.0, 4.16rc3 kernel (tested 4.15 and had the same problem)
