General artifacts shortly after CPU warming up

I've got these artifacts after upgrading from 17.0.5 to 17.1.0:
I thought it was a kernel issue as it is much more prevalent on kernel 4.11.2 which got updated at the same time. At first I reverted to 4.10.9 and thought it has been fixed but then I noticed that the artifacts were just always vanishing more quickly and were lighter, on 4.11.2 they were left static at the screen in case I didn't move/input anything.
These artifacts always show up shortly after I boot the PC, but not just after booting. I need to play some video on youtube to warm up the CPU or something and when I scroll text on the web they show up more sharply to the point that it's really annoying. Despite that, these artifacts are present in some form or another with any application, not just the browser.
I've initially reported it here, where Xorg logs can be found:
I'm now on kernel 4.11.3 without any issues using mesa 17.0.5.
