Content randomly flashes white when switching app to foreground

ionic-v1
1

Hello, please bear with me if this is obvious.

I’m almost finished writing an Ionic v1 app, but I’m having an issue which I don’t know how to even begin to debug.

It goes like this:

  1. I open my Ionic app on a mobile device (usually in Android 6.0.1 but have also tested in iOS)
  2. I put my app in the background, for example by switching to another app or just tapping the mobile’s home button to see the “desktop”.
  3. I put my app back again in the foreground

The problem is that sometimes when I switch back to my app (third step), the app screen content flashes white for a moment. This “moment” ranges from almost imperceptible to 5 seconds or so (it varies depending on I don’t know what). Many times, however, the content will show without any white screen at all.

Is this expected behavior? Or does anyone have an idea what could trigger such a thing?

Thank you!

My ionic info:

Cordova CLI: 6.4.0
Ionic CLI Version: 2.1.8
Ionic App Lib Version: 2.1.4
Node Version: v6.9.1

Hello,

Can someone think of anything I might look for here?

Thanks a lot
