Alright so I decided to give this a try since I have some time. I downloaded
the mesa-git and lib32-mesa-git tarballs manually and ran makepkg -s then I
went into src/mesa and used that command to put in the commit and went back to
the main directory and did makepkg -s instead of makepkg -efsi because I don't
know what that does...I believe -i installs it but I would prefer it to make
.tar.xz packages so I can remove this version using pacman....I am just afraid
to screw up my system. So I did this for mesa and lib32-mesa to ensure nothing
would go wrong, and it seemed to have built mesa-git 10.6.0_devel....

Alright, I did sudo pacman -U to install the .tar.xz packages that were built
logged out/in and loaded up CSGO. The graphical issues I have been talking
about are still there. I went into /src/mesa did bit bisect start and then git
bisect bad and put the ef7e0b39a24966526b102643523feac765771842 commit.


I honestly have no clue what I am doing but I then did the same steps initially
of building the package but did commit    
cb154bb22116910c462f7a83f4401bd01e15c34d which is a commit for 10.4.7 since the
entire 10.4.x series were fine with CSGO and only noticed issues since 10.5
came out. I guess ill move up from 10.4.7 and there? Again I did makepkg -s and
the .tar.xz that were made were the same ones as before. I am confused if I am
actually doing anything here.
