Comment 12 for bug 1654583

Came across this issue again since bug 1701966 was just reported.

Since this was initially filed, a newer version of Mesa has become available in Ubuntu 16.04. (https://launchpad.net/ubuntu/+source/mesa) I don't know whether this will affect much in practice, but doesn't hurt to try. Could you check that you have all updates installed and retry Widelands? If still doesn't work (or even if it does), could you attach the updated glxinfo output?
