Glxinfo output
Hi, I use Linux Mint 18 (Ubuntu 16.04) on my Thinkpad T510i. I am using an
updated Mesa PPA (Personal Package Archive), I tested this and it is happening
on 2 well known PPAs, oibaf & padoka. These ppas provide updated Mesa from git.
I noticed this issue when trying to load up Minecraft. This issue only happened
recently. The result is weird color issues, triangle rainbow
flickering/artifacting on every texture, etc. See the screenshots linked below.

If I revert back to the distribution-provided version of Mesa, 11.2, there is
no issue. So I don't think it's my hardware.
Another weird (might be related issue) is if I try to record my desktop, after
playing Minecraft, instead of my desktop background showing in my recording, it
shows a dirt block from the game Minecraft. However, I don't see that image
from the game until I record and watch the video. It doesn't show on the "real
desktop".
This only happened in recent updates, previously, using updated Mesa worked
fine, and provided improved performance.
Here's my hardware and kernel info:
Kernel: Linux 4.4.0-51-generic x86_64
Distro: Linux Mint 18 Sarah
CPU: Intel(R) Core(TM) i5 CPU M 520 @ 2.40GHz
4 cores/threads
2400.00 MHz
RAM: 3.66 GiB
GPU: Mesa DRI Intel(R) Ironlake Mobile
OpenGL 2.1 Mesa 13.1.0-devel - padoka PPA
GLSL 1.20
Attached is my glxgears output (Sorry if you don't need this, this is my first
time posting a bug on Mesa bugzilla)
I also experienced artifacting in the game "Edge", on the menu screen.
