[winswitch] Dynamically variable DPI?

I'm using xpra+subuser for most things now. It works well, except for 
full screen videos on my high-dpi display, which don't play well at all. 
All of this is local, and as far as I know, I have compression turned 
off and memmapping turned on... If I play the videos in non-fullscreen 
mode then they play fine. It seems to me that since youtube videos 
aren't actually high dpi anyways, then there shouldn't be a difference 
between how well they play in non-fullscreen mode and how well they play 
full screen. Would it be technically possible for xpra to detect that it 
is being slow, and to automatically start passing a lower dpi version of 
the window contents? I don't know if that's crazy or not, as I don't 
know how xpra internals work...
