    FWIW: Since Debian released 17.3 rc5 in Experimental to Debian Sid for proper 17.3 today it is COMPLETELY BROKEN on GNOME 3.26.2. The dreaded, ``Oops, Something went wrong,'' logout loop until a hard reboot, go into single user, change to console text boot, update-grub, systemctrl set-default mult-user.target hurdles, downgrade to 17.2.5 restore graphical target and grub prior states for a useable desktop once more.

    Seeing as nothing worth a crap is listed anymore in Xorg logs I'll stick to 17.2.5 until Debian does their job and tests the product over its usual chroot ``worked for my system, ship it'' approach gets tossed out on its rear end.

      Ubuntu 17.10 stock Mesa 17.2.2: Decent OpenGL performance, Vulkan not working due to Mir patch
      Proposed repo Mesa 17.2.4: Same OpenGL perf, Vulkan now working but causes graphical glitches and slightly less perf than OGL.
      Padoka PPA Mesa 17.4git: Noticeably better OpenGL perf, Vulkan now working without glitches and is slightly faster than OGL

      Don't remember the exact numbers, but 17.2 OGL was averaging around 84fps I think and my initial Vulkan testing was probably just below 80fps. With padoka OGL was just above 90fps while Vulkan was close to 100fps.

      I see the similar results on my Fury/FX8350 combo.. as for the graphical glitches with Vulkan & Serious Sam Fusion is it started with LLVM rc3. I first noticed it back at the end of June/July with Padoka's ppa but there were updates to too many other packages including SSF to know which one. When Oibaf added llvm 5 initially everything was fine up to rc3. Sadly I don't grok git fully to actually pinpoint the cause.
