Code review comment for lp:~alan-griffiths/mir/fix-1717910

No change. Try a command like this:

QT_LOGGING_RULES=qt.qpa.*=true QT_QPA_PLATFORM=ubuntumirclient /usr/lib/x86_64-linux-gnu/qt5/examples/webkitqml/flickrview/flickrview

Qt is getting the resize event from Mir, but we've never trusted the resize event from Mir as it seldom reflected the next buffer size - so instead we forces a redraw, which pulls a new buffer from Mir, and we check that buffer size to see if it changes. We're not getting any buffer size change.

OFC adopting the new buffer semantics stuff would probably rectify that. But that's non-trivial work
