QScrollArea renders incorrectly when grabGesture is set to TouchGesture

As mentioned here under certain conditions a QScroller configured to use touch gestures or lmb gestures on android will exhibit substantial rendering bugs. Ghosting/tearing, and upon release some sections of the screen don't redraw. I don't preclude user error, but considering it's a rendering issue it feels plausible it's a bug so I'm raising this here.

I've included the sample and image that the other user posted, as well as an example of the issue in my application. Note that in this second image, the one where it appears the view has been dragged down, this is after it has been released. It is not rerendering the top half correctly. I can prepare an additional code sample if the one provided by the original poster is incorrect, however the application I'm working on is fairly large so I am reusing theirs out of conveniece

As always, I apologize if this is not the correct place to raise this, however this is fairly urgent for my team

EDIT: I had the thought that maybe it is user error? Is it possible I've built the libraries without a necessary graphics api provider? I've attached my  config.summaryI am not totally sure which the relevant sections are but I notice that the only backend I appear to have built for is OpenGL ES2.0.
