You can google on how to check the compositor settings in Linux Mint. By default, the compositor should be enabled. If you haven't touched this setting, it’s likely still active. If that's the case, I’m afraid I can't provide further help... Here is my graphic info, everything appears to be identical to yours. 0ad works fine on my machine, so I guess the reason might be something else. Hope this helps. Edited: btw, I use Xfce, so there could be some differences.

did you disable compositor, like it suggested in this link? I use Linux Mint as well and noticed that my screen flickers when I turn it off. The flickering goes away once I re-enable the compositor.
