Openbox crashes when opening Unity3D games

[Leonardo Müller]

Hello

I use Lubuntu 16.04 and when I try to open any game made with Unity3D, the computer presents different issues. It may:

-Open the game correctly (rare);
-Make Openbox crash and recover and the game is not visible even if it is still running (rare);
-Crash Openbox with no recovery than restarting lxsession (common);
-Crash the whole Xorg or lxsession (uncommon).

The higher the resolution of the game, more prone it is to errors. As a (very bad) workaround I had configured all games to open with a 800x600 window.

While sometimes appears the apport window pointing to Openbox, Xorg, Lxsession, Steam or even Skype(?), I suppose Openbox is the responsible because I noticed it was the first, and sometimes only, thing to crash.

To test my hypothesis, I have installed different alternatives to openbox: marco, metacity and xfwm4. None of them suffer from similar issues and I can open the games at 1366x768 with no issues. I decided to use xfwm4 instead of openbox as default due to this problem.
