    Description

      Flickering has been observed with this setup:

      Configuration: Ubuntu 13.10, i915 stock intel, graphics 3k (i5-2520m)
      GL_RENDERER: Mesa DRI Intel(R) Sandybridge Mobile
      GL_VERSION: version: 3.0 Mesa 9.2.1
      GL_VENDOR: Mesa Project & SGI

      Both LIBGL_ALWAYS_SOFTWARE=1 and QSG_RENDER_LOOP=basic|windows fixes the issue, but forcing llvmpipe also introduces issues with context sharing. We can disable ThreadedOpenGL from the platform plugin to force one of the other render loops.
