SMC does not work for me.
Disabling 3D acceleration for my Parallels Windows VM does work, if you can call it that. It's incredibly slow and not a real solution, but it may help point to the root cause of the problem.
@Carlo you said that the DisplayLink team currently can't reproduce the problem after SMC. Can you confirm whether or not you're doing any testing with Parallels VMs, or only native host windows?
