Are you familiar with compiling wine from source? If so, we could check the above theory.
No, but I can try it. I have now get Wine from git and made my first try. It failed due to missing dependencies and I tried to install them like suggested in the Wiki (I'm using Ubuntu). But resolving the dependencies failed (which is unfortunately not rare on a build-dep with Ubuntu). I will add the log as an attachment. Maybe you can say me what I have to do now.
I guess that's not a widespread one among GW2 players. If it is somehow related to the problem, this might explain why nobody else reported the issue. To either confirm or refute Openbox being the cause, you could thy another WM... say xfwm.
I have now uninstalled LXDE with Openbox and installed Unity with Compiz. After a reboot I have tested this again but the problem still exists.
