Roon mini-player displayed on TV via Roon Ready ready receiver - how would I eliminate it?

I have an Integra DRX 8.4 receiver which communicates very nicely with my Roon Server. But here is my problem - I also use the DRX as a Home Theatre manager with a Movie PC, etc. sending various signals to the DRX and then, possibly, on to my TV. In the situation where I would like to use Roon while viewing content on a PC (say a photo slideshow) the DRX will always superimpose the Roon mini-player on top of any PC content (albeit in an optional, mini format in a lower corner of the screen). This is probably a receiver issue, not a Roon issue but I’m looking for ideas/suggestions to eliminate this inconvenience.
