When I have "Pokemon Go" running, and I double-click the "home" button, I sometimes see a blank window in the list of apps that can be scrolled through by swiping to the right. I've only seen this happen with "Pokemon Go." And, the app functions just fine with, or without it.

What does that blank window represent?

btw: double-clicking "home" not only shows running apps, but also recently run apps, right? Yet, I've never seen "Pokemon Go" in the list other than when it is explicitly running (never as a recently run app). So, I'm a little confused.

  • Is the blank window 'in place of' or 'in addition to' Pokemon Go?

  • @fsb In addition to. While the Pokemon Go app is running, it always is correctly displayed in the list of apps that are shown by double-clicking "home" . Then, sometimes, an extra window (that is blank) is displayed in that list. The only reason I know it is related to Pokemon Go is (1) killing, with a swipe-up, Pokemon Go also removes the blank window, (2) observation. I've had to re-start Pokemon Go so much, I started noticing that extra, blank, window, and Pokemon Go was always running at the same time.

  • What is the title of the blank window? The title should be at the top when you're scrolling thru the apps.

  • @fsb I got lucky. It just happened again. I added a screen shot.

  • @fsb ok. I'll start paying attention to whether the issue is only with the "Settings" window.

(Answer added from the comments)

Check the title of the window when you're in multitasking mode. Some windows are either 'blanked' or 'blackened' in this mode to hide sensitive or proprietary info.

The window will refresh once it receives focus again.
