Drawing overlapping rectangles over a View freezes the application

[pm-ur]

I've been displaying an OSG View and I was able to paint a rectangle over it fine. However, when that rectangle has another rectangle in it, the application freezes.
Just found this issue. Will post more details once I investigate it further.

Hi @pm-energid! More information about your environment and code examples are highly desirable for reproducing this fault.

Hi @podsvirov ! I am trying to run a simple code as this:
`import QtQuick 2.0

import osgViewer 2.0 as OSGViewer

OSGViewer.View {
id: view
width: 400
height: 300

Rectangle {
width: 100
height: 100
color: "red"
}
}`

There is a short freeze while the rendering loads and then I can resize the window. If there are any elements like buttons, I cannot interact with them any more. Also, resizing the window doesn't update the changes due to size either. The attached video shows the behavior.
