Me a year ago: "yeah I know opengl drivers are buggy but this is just a 2D game engine, it's not going to do anything fancy at all. Shouldn't be an issue."
Me now: "I need to make a FAQ dedicated purely to graphics driver bugs we find."
@Nentuaby I don't know how that seems possible, since 2D is a strict subset of 3D. Ie, everything you draw is a 3D mesh, just a flat one being displayed from a fixed angle.
