Description
Run this in qmlscene. If bug is true, it will render a window that is 50% white, and 50% green. If bug is false, the window is 100% green. If you do not set the render target, the bug is gone. Setting a canvasSize has no effect on the bug.
This seems to be quite a nasty rounding error.
The only workaround we have found is to not render so small things.
