Severe FPS degradation when a video is played via the Video Player Component in the WebGL build
Reproduction steps:
1. Open the attached "FPSDropWebGL.zip" project

4. Observe the FPS counter in the top left of the Player window
Expected result: FPS does not drop down when the video starts
Actual result: FPS drops down significantly
