turing-fluid demo corruption

GFX_OGL turing-fluid demo shows substantial display corruption (attached) with
a GL-composited window manager, the Chrome web browser, and a cloned HDMI+eDP
display configuration. The corruption becomes worse over execution time.

This has been reproduced on multiple hardware configurations (where HDMI+eDP is
possible) and multiple Linux distros.

Steps to Reproduce:

1. Boot to a GL-composited window manager

2. Connect HDMI +eDP, display clone (not extend)

3. Open Google Chrome web browser

4. Run the below WebGL Demo:

5. Check the behavior of colors over the Window and click on the same
