Description
We noticed that there is a significant performance drop in Audio Visualizer while verifying that the bug (RT-31881) that broke it was fixed. By examine the changeset that fixes the bug, we believe the cause is due to the trashing of texture as the 3D transforms of the 2D rectangles were animating:

Comments
Note that the above changeset which fixed the rendering issue described in RT-31881 was for RT-39120, and that also introduced the slow rendering.
