While investigating my laptop's power consumption using "powercfg /energy" I noticed that ScreenshotCaptor is now listed as one of the processes that use the CPU in such a way that prevents it from being switched to its lowest-power mode. This was not the case previously (before 4.8?).
Process Explorer seems to reveal some sort of polling: see the huge number of cycles and context switches in the attached screenshot.
Can you please look into this (and fix the issue)?
