Map Overlays in Rendering Debugger causes Game View to glitch when shaders are compiling

To reproduce:

1. Create a new template project
2. Open Rendering Debugger window (Window > Analysis > Rendering Debugger)
3. Enter Play mode
4. In Rendering Debugger window, set Map Overlays to Anything other than None

Result: Game View is glitching, looks like it happens until shader is compiled (see the status bar on the right bottom corner)

Notes: 

• It cannot be reproduced after shader compilation is complete, so you need to create a new project and try again. 
• First few frames right after entering play mode also results in glitches.
