I believe my engine is using the OpenGL rendering system, which means that when using SDL_RenderSetClipRect (and only this function), the coordinates of 0,0 are for the bottom left of the screen.
If I change to use DirectX, with the x,y coordinates change so that 0,0 is the top-left of the screen, or will it stay at the bottom right ?
Are you mixing the SDL renderer with your own code or just using the
renderer? Because the SDL renderer always uses the top left as 0,0.

I believe the origin for the opengl driver has been fixed to top-left (see SDL_RenderSetClipRect bug with openGL and a Texture as render target · Issue #1616 · libsdl-org/SDL · GitHub). From my testing,
clipping works now. I switch between the software opengl renderer drivers and no longer need to do anything special with clipping coordinates.

Just using the SDL2 renderer for everything…

Ah, so it looks its been fixed. I’ll have to get an update for the beta at some point then
