Interesting discussion: obs studio: Add proper color space conversions
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.
