I've been trying to figure out the cause for this bug for quite some time now.
Here is the bug ticket on the dota2 github page:
https://github.com/ValveSoftware/Dota-2/issues/1368

Since about one week ago, I have been unable to start dota2 on my machine. This
happened after I updated my llvm and mesa git version.

If I downgrade to mesa 17.3.1 it works again (without reboot). But it seems to
be really hard to track down the commit that broke it as there seems to be some
kind of cached behaviour (not the mesa shader cache as I removed the directory
and rebooted several times).

For example I downgraded mesa to a commit from 2017-11-17 and it worked. The
next day I tried to figure out the commit that broke it. But I could then use
the git master version and it seemed to work fine again.

Then the next day I'm back to the same problem and I downgraded again and now
it won't start again even if I use mesa from 11-17 (and rebooted). But 17.3.1
still works if I downgrade to that... (no reboot)

I really do not know how to debug this further as I don't know when I'm on the
commit that broke it or not. However it seems to always break if I'm on a
commit that is newer than 1-2 weeks (after a reboot that is). However it will
not fix itself with reboots with commits older than that either...
