Something suspicious to me, the GL context Mir is giving to Qt is missing the alpha channel:

Settings "QSG_INFO=1", you get:

qt.scenegraph.info: texture atlas dimensions: 2048x2048
qt.scenegraph.info: R/G/B/A Buffers: 8 8 8 0
qt.scenegraph.info: Depth Buffer: 24
qt.scenegraph.info: Stencil Buffer: 8
qt.scenegraph.info: Samples: -1
qt.scenegraph.info: GL_VENDOR: Qualcomm
qt.scenegraph.info: GL_RENDERER: Adreno (TM) 320
qt.scenegraph.info: GL_VERSION: OpenGL ES 3.0 V@53.0 AU@ (CL@)

the A Buffer should be 8.
