graphics and javascript problems

[clever_nick_here]

I can't play 0ad currently. The problem seemed to start when mesa and related packages were updated to mesa 10.3.1-1, though this could have been a coincidence as i don't get to play but once a week or two. I was still using 0ad 16.4(? or whatever was previous to 17.1 in arch repos) then. the problem persists with 17.1 unfortunately.

the problem: when i start 0ad the graphics are very corrupted looking and i can't get any button in 0ad gui to do anything except make input sound effects. 0ad also shows javascript errors. I have to exit runlevel 5 and restart gdm to get back to my desktop, though there may be a shortcut i'm not aware of to get out of crashed 0ad.

thanks in advance
