There are some failing shaders in the log, this might have been fixed by some
register spilling work in the llvm, you may try to get a never llvm and mesa
from some ppa (dunno how that works on Mint), or compile them yourself.

Also I'll give you few hints how to write better bug reports so people can help
you more ;-)

1) One problem per bug, e.g. don't recycle old bug reports for new problems as
you did in comment 16, open a new bug.

2) For 3D stuff such as games, the most important component isn't the xorg
driver, but the mesa (3D driver), llvm (for Radeons) and kernel. It is
important to always post which version of those components you have installed.

3) Always describe exact steps how to reproduce the issue. This means full name
of the program, version, download links if available so people can reproduce it
and help you. 

3) Posting screenshot is also a good idea. Another interesting info is output
of glxinfo (this shows your mesa and opengl version and extensions), dmesg
(kernel output), but usually developers can ask for those. 

4) If your versions of mesa, llvm or kernel is lower than latest versions, it
is possible that your problem was already fixed in the latest version (which
also may be the case in this bug). In that case try to get latest version via
your distro or some ppa or compile it by yourself and test it before filling a
bug. This could save developers a lot of time, by not having to look at already
fixed issues. 

Sidenote: also pay extra attention to the 32bit vs 64 bit stuff, 32 bit
programs (most Steam games and closed source games) need 32bit mesa, libdrm,
llvm, libtxc-dxtn etc... so always double check that you indeed have the right
components installed or that you upgraded the right ones.
