[REG 5.7.0-5.7.1]: When disabling a QSurfaceSelector it can cause it to stop rendering on all the windows rather than just the one using the selector

When disabling a QSurfaceSelector it can cause it to stop rendering on all the windows rather than just the one using the selector. This is caused by 885610d28e183b8f49b7f5adc50223cd096d3286.

Additionally there are issues with the order that children are created related that is introduced by the same patch. In this case it can cause some aspects not to render even though changing the order of the children will make them render correctly.
