What I expected to happen was...:
Shift+F3 menu to open/close like normal
What actually happened was...:
Shift+F3 menu opened like normal but when closing the F3 menu, the debug pie chart remains frozen on the bottom right of the screen.
Steps to Reproduce:
1. Click Shift+F3.
2. Close the menu using F3.
3. Observe bottom right corner for debug pie chart.
