@substring OK, fine - but actually the Recalbox IS running hot when Nothing is Happening in EmulationStation. This is a "new" behaviour. I never saw the temperature Icon on my RasbPis before, even during N64 Emulation. Can we agree that an idling ES on an NOT overclocked RPI3 should not drive the CPU over 75 Degrees Celsius?

@substring I think I can confirm the behaviour that @ulao is trying to tell us here. When I leave Recalbox running after a certain number of minutes without a keypress it loses Connections to Xbox Wireless Controllers. To revive Recalbox I Need to unplug and replug the wireless Adapter into USB. To my best Knowledge that did not happen with earlier builds and seems to be a June-2018 Problem, but I could be wrong here. But I do confirm that Recalbox now loses USB Controller Connections after periods of inactivity.

@raffols @substring I can confirm this. When ES is running, one of the cores of the RPI3B is running at full 100% constantly and leads to the "Thermometer" Icon in the upper Right Corner. Switching into a game usually stresses a second core then. Somehow there seems to be a Process running constantly that eats cycles. It's not Netplay, I turned that off (unless it still is running, just not doing anything?). Never had overheat warnings with earlier Recalbox Releases. API is turned off too (Web Manager is on).

Again, just for clarity: Turning on Recalbox, doing Nothing, just keeping it at whatever screen it is when starting (with me, Favourites) will after an hour max lead to temperature warnings and one core is constantly at 100%
