Description

The optimization view mode 'Quad Overdraw' image is not properly cleaned up when switching directly to 'Stationary Light Overlap' view mode. See attached images. 

Steps to Reproduce
  1. In perspective viewport, select View Mode > Optimization Viewmodes > Quad Overdraw
  2. Next, change from 'Quad Overdraw' to 'Stationary Light Overlap' viewmode.

Result: Lines on screen from Quad Overdraw remain visible even though viewmode has been changed to Stationary Light Overlap mode. The lines are transparent and superimposed over the viewport but remain static relative to camera position. 

Expected: Stationary Light Overlap viewmode would appear without the lines from Quad Overdraw.
