After 1-2 minutes (varies) the game starts to react to input and produce sound and apparently "works" without too much lag BUT the screen stays still black. Sometimes the game manages to play the Blizzard intro screen sound immediately when started, so apparently there's no inherent lag in the startup but only somewhere later.
With Xnest, the game displays correctly and actually works better than I remembered. (Unfortunately, running two instances simultaneously makes them both lag.) With Xephyr, it's the black screen.
Conclusion: not working. I'm not entirely sure if there's any change, because I didn't test it like this before.
