Not that surprising.
Without the UI showing, once the video is playing then the CPU is basically shovelling data from the network to the GPU and the GPU is doing all the work.
Once you add the UI, then I suspect the CPU has to decode the video so it can overlay the UI on it before feeding the decoded & modified video to the GPU. If there's any way to see the processor load in the GPU then I suspect you'd see a corresponding drop.

The ideal would be to be able to keep shovelling the raw data at the GPU and have that overlay the UI as it decodes the video - but I suspect the architecture of Mythfrontend would need some major remodelling to support that.
