Can anyone explain this?

Top one is using SDL git mirror repo.
Bottom one is using SDL 2.0.3.
This is run on the same machine, windows 7.

I don’t see any commits that have to do with color/brightness/gamma from the release of 2.0.3 to hg/git HEAD of b577c4753421, so, what could explain why 2.0.3 is so much darker than the git/hg repo?

Also note, they were both run in a window, not full screen, and I am not using any special calls like SDL_SetWindowBrightness() / SDL_GetWindowBrightness() / SDL_SetWindowGammaRamp() / SDL_GetWindowGammaRamp() / SDL_CalculateGammaRamp().

Platform/renderer backend? First thing coming to mind is the ImageIO
gamma fix on OSX, although I don’t remember when exactly was that

Using openGL directly, SDL 2 just sets up the window.
No SDL calls to draw anything.

Nope, nothing SDL related to load textures.
SDL only handles input & screen setup, nothing else.
