    Qt 5.4.1, Android API 16, standard emulator - same problem. In emu qt quick buttons/interface is not drawn. (though it reacts to "touching")

      Tried genymotion - same thing.

      So that means that qt quick projects are basically not "debuggable" on pc without device on hand? That's bad.

        Hi,

        I'm not completely sure but I recall something about activating the GPU emulation for the emulator.

        Hope it helps

          I had use GPU Host enabled.
          Disabling it produces same result but with these errors:
          @E/libEGL ( 1079): called unimplemented OpenGL ES API

            I tried it on my notebook (8.1 x64 too) and there it runs fine. So it's most certainly some kind of bug/misconfiguration.

              Maybe an OpenGL driver issue

                  Could be but how to test? I run some simple OGL benchmarks and they work fine, I have latest drivers, OGL is 4.4 version. If it was driver/vendor-specific issue there probably would be more reports by now.

                      R9 290, CCC 14.12,

                      I tried OpenGL ES samples provided by emulator and they worked fine, so it seems qtquick/the way it does something-specific.
