H264 is currently disabled in the HTML5 client, the latest betas builds

FYI: client applications should be started with "xpra --start=THEAPP"
rather than by hand with DISPLAY= to ensure the whole environment is
correctly setup.

I'm not sure if and how "atom" and docker are relevant to your question.

since we only get limited keyboard data.
For debugging, see:
