Bug Description

Start app with QT_LOGGING_RULES="qt.scenegraph.renderloop=true"

You will continuously get:
qt.scenegraph.renderloop: polishAndSync (normal) QQuickView(0x204ca58)
amongst many others, which indicate that the UI is being redrawn.

Even with occlusion enabled, we still get:
qt.scenegraph.renderloop: - ticking non-visual timer

There may be a hidden activity indicator which is set to running even though not visible.
