At this point, Cinnamon Desktop is more important than Mythtv on those 2 
machines because they are more personal computers than MythTV frontends. 
My wife uses the FireTV 4K stick and I use Nvidia Shield TV for 99% of 
our TV watching, a combination of Mythtv recordings and internet 
streaming services.

However when I've used MythTV on any of our PCs the GT-710 and GT-1030 
have performed well using the Software OpenGL Normal profile.

So that's a long way around saying that having Compositing on isn't 
really a problem for us.
