Steps to reproduce

  1. Run iosapp.
  2. Send the app to the background.
  3. Reopen iosapp

Expected behavior

The app should reopen.

Actual behavior

The app displays a white screen, with the following console output.

Assertion failed: (gfx::BackendScope::exists()), function reduceMemoryUse, file /Users/Kiley/Desktop/repos/mapbox-gl-native/src/mbgl/renderer/renderer_impl.cpp, line 226.

@jmkiley is this happening 100% of the time?

@tmpsantos Yes, I see this every time iosapp is backgrounded. (Or, presumably, any time an app integrating a debug build of the maps SDK is sent to the background.)
