It doesn't happen on my non HDR monitor. The effect only appears in modes where ambient light is enabled (fullscreen and theater for me, but when its in windowed the effect doesnt appear)

I think you might have missed #129
UPDATE: I've now also added the current level of browser support for HDR color spaces to #129
