Description

To reproduce the problem run the following code:

import QtQuick 2.5
import QtQuick.Window 2.2

Window {
    id: win
    visible: true
    width: 200
    height: 200

    Canvas {
        id: canvas
        width: 100
        height: 100
        contextType: "2d"
        renderStrategy: Canvas.Cooperative
        renderTarget: Canvas.FramebufferObject
    }
}

On linux it works on Win7 it crashes, changing the renderStrategy or renderTarget makes it work, also setting the SG render loop to basic.
