Google chrome is now enabling HDR video playback on Windows 10.
So we may need to start looking at this sooner than planned.

See also: When to call glEnable(GL_FRAMEBUFFER_SRGB)?: When GL_FRAMEBUFFER_SRGB is enabled, all writes to an image with an sRGB image format will assume that the input colors (the colors being written) are in a linear colorspace. Therefore, it will convert them to the sRGB colorspace.

Also: That is almost certainly due to Intel sucking at writing OpenGL drivers. lol.

Relevant: #1155.
