Hi, I installed from oibaf-ppa and got version 10.3.0-devel (git-15b5e66
trusty-oibaf-ppa) but unfortunately I could not start any game with it, I only
got several error messages, so I rollbacked to 10.1.3 :-/

10.1.3 is the version released with Ubuntu 14.04 which is from May, I saw that
the 10.1 branch is now in 10.1.6.

I've been looking to the commits of the 10.1 branch but could not see anything
relevant to that problem. I would like to know more about it and perform a step
by step debugging inside Mesa code but for that I need to know how to build a
debug version and make Ubuntu use my built version instead of the real one. I
have no idea how to do it unfortunately :(

Maybe spying OpenGL calls until the fatal call to glDrawRangeElementsBaseVertex
would help too. I heard Valve made a tool like that but I am not sure if it can
act as an OpenGL validator.

Hi. The bug you are referencing describes a crash that occurs later in the game
so I am not sure if it is related with the bug described here that occurs at
the start of the game when the menu is about to be shown.
