Could you confirm that? CreateSprite(0) should create a blank, empty white colored sprite which can be colored with SetSpriteColor(). With older Versions it worked fine, but with the new studio version (2019-09-17) only black or multicolored (!) boxes are drawn. Maybe an addressing failure? The issue only occurs with basic renderer (#renderer "Basic") and if an image sprite is rendered in the background. Strange look ...
I attach an example and an image.

I filed a bug for this issue. It appears to me that it only occurs on windows and not mac. I even have the renderer set to basic

That is strange, I can't seem to replicate the problem on any of my Windows machines, one has an AMD GPU, the other an Nvidia GPU, both work as expected. This is what I see

I've managed to track it down and fix it for the next version, for some reason it only affected Intel hardware

Yes, OpenGL requires that vertex attributes be set with glVertexAttribPointer before drawing a vertex buffer. AppGameKit attempts to optimize this by only doing it when necessary, so previously it only did it when switching vertex buffers. However it should also be done when switching shaders, it seems AMD and Nvidia GPUs don't mind, they must be storing the settings differently from Intel.
