      Description

      OpenGL crash on start on Intel + AMD GPU systems

      All Qt applications that try to create OepnGL context crash on my systems with Intel GPU and an AMD HD 7950.

      • Mininal repro with Qt OpenGL examples like the hellogl2
      • Qt Creator also will crash the AMD driver on start.
      • Need to have two monitors : one connected to the AMD and the other one to the Intel GPU DVI port.
      • Main Windows Display has to be set to the AMD monitor (use Win10 system / display settings as shown in the attachment)
      • To repro the crash start the application on the Intel window.

      No crash if you start the application on the AMD window / monitor.
      No crash if Intel monitor is set as the Main monitor
      No crash with other GPU vendor combinations (i.e. Intel + NVIDIA ).

      – Other OpenGL applications seem to run fine on the systems that can repro this.

      Typical system configuration for a repro:

      • Desktop motherboard + Haswell or Skylake CPU with integrated graphics like HD 4600 or HD 530
      • Also plug in an AMD HD 7950 to the PCI-e slot
      • Install Windows 10 and all the latest drivers
