[macOS] QGLWidget becomes unresponsive

In an application that consists of main QGLWidget and a docked widget that contains another QGLWidget the application stops responding when switching to full screen mode.

Sometimes the application can become back to responsive if switched between applications after the full screen mode has been enabled.
After adding 2 instances of main QGLWidgets the issue vanishes and application works fine even in full screen mode.
The exact same application works fine on Windows.

Steps to reproduce the issue:
1. Run attached test application
2. Switch to full screen mode

Expected outcome:
Application remains responsive

Actual outcome:
Application doesn't react to any mouse events
