OpenGL only supports binding a limited number of textures (e.g. 16) at the same time, but now I need to use a higher number of textures in once glBufferData-glDrawArrays call, how can I use more than 16 textures in this process?

I attempted to implement a readback of a drawn framebuffer for auto-exposure, but no matter what I try, either glGetTexImage or glMapBuffer stalls.
Am I doing this wrong, or this this an issue with my particular machine, because I can’t observe the stalling on my notebook.

I’ve recently watched an interesting video about domain modeling in F#, and I wanted to apply some of the concepts to my C++ code.

So I followed The Cherno’s Game Engine series and now created the batch rendering system, I followed it, but the textures seem to flicker, like if OpenGL tries to mix two textures. Here is the fragment shader:

I checked everything multiple times, and didn’t find any of the common problems i found on stackoverflow, reddit, and stackexchange. I’m trying just to render a rectangle with a texture at the moment, but it is invisible (if i try to use a basic shader the rectangle shows up correctly).
