    OpenGL geometry shader freezes driver (Intel HD 4000)

    Asylum2010

      Using a geometry shader to render lines causes the driver to freeze the computer.

      Source code can be found here: asylum2010/Asylum_Tutorials · GitHub

       

      Repro: build and run the project titled "23_MultiThreading" -> driver freezes. After a while it resets.
      The shader is loaded at framework/drawingitem.cpp:59.

       

       

      If I replace that string with 0 (so the geometry shader doesn't get loaded), then the program works fine.
      If I load the geometry shader but I don't use it, then the program still works() !

       

      (note: ignore the fact that I use multithreading, it has nothing to do with it !)
