I honestly don't know the degraded performance Martin was speaking of. Maybe it's something you can only noticed in a timed performance test application. Not sure you would be able to detect it with the naked eye. So maybe the easiest solution is no not use that x11 feature - seeing as the open source drivers are pretty terrible anyway, and I doubt a fix will come in the next decade at least.
