If you're in full screen mode and you try to access the drop-down menu. You can still interact with them, but they won't be visible. This appears to be an OpenGL mode only problem from how I tested. Reproducible: Sometimes Steps to Reproduce: 1. Make sure OpenGL is active. 2. New/Load document 3. Go full screen 4. Click any option in the menu bar at the top of the program. Actual Results: No drop down menu visible. Can still interact with drop-down menu. Expected Results: Show the drop-down menu. OS: Windows 10 GPU: nVidia GeForce GTX 750 Ti
This is a bug in Qt, we "solved" it by removing the fullscreen option on windows :-(
