It works just like the solution in this link: https://stackoverflow.com/questions/64837705/opengl-blurring
I even scaled down the bloom framebuffer's resolution so that the bloom would be lower quality (which is ok, since it's meant to be blurry) and faster.

Indeed, I'm seeing this first hand. The problem is that the gradients and weak strokes are getting sharper, and it ruins them. There may be a way to fix this however. Some of the RGBA layers get assigned with a multiplicative blending "color", those are always used for shading (helps increase color variety). All I have to do is ignore the multiplication layers, then the outlines and fills will get sharper but the gradients will not.

Ugh, now it looks just like an adobe flash animation. I kind of hope no one plays this game in 4K.
