The bottom bar has 3 app launching buttons. Tap one, the app will start and slide in. On the left is a black rectangle - tapping this fetches a new snapshot of the application.

Like lp:1263741, this is a side-effect of occasional GL_OUT_OF_MEMORY errors when trying to read the pixels from the FBO backed by the application surface texture in GLPixelBuffer. Fixed by lp:~kdub/mir/fix-1238695 .
