Portal Calendar + Screensaver?

Hi all,

Taking advantage of the newly-unlocked Portals, I bought a cheap Portal Mini 2 and set up Portal Calendar, which is very nice, as well as the Immortal screensaver...

The problem is that if the calendar is open, it does not go to the screensaver, I only see the options of having the calendar on all the time (no good in terms of screen burn-in and general aesthetics) or exiting the calendar, which makes the screensaver run fine.

So, is anyone successfully running a Portal with an open Portal Calendar + the Immortal screensaver? Or some other solution, like the GPhotos screensaver?

Thanks in advance for any help!
