      When an OpenGL context is created during global initialization phase of a plugin (and the main application does not use OpenGL), it hangs for some reason.

      Attached a minimal project that reproduces the problem.

      If you copy the initialize function to main.cpp (with Q_COREAPP_STARTUP_FUNCTION), it works as expected.

      WebEngine has a similar initialization sequence.

      I did not try to upgrade the Radeon driver, so that I can reproduce the bug consistently.
