    Description

      Under qt 5.3 and 5.4, when using Angle for rendering, qml Image elements with mipmap filtering sometimes display as blackboxes.

      I have seen this on a machine with an Intel(R) Q35 Express Chipset, running driver version 8.15.10.1930.

      Attached a test project showing the problem as well as some log output with qt.qpa.gl logging and QSG_INFO=1.
