Graphics (speaking of modern 3D graphics) on Linux sucks, because NVidia and Co do not really care about it. It has gotten better (e.g. the deep learning crowd is mostly on Linux using cuda), but is still a far-cry from the stability of other sub-systems. So I would say it is mostly gaming. There are not many games on Linux (again, getting better, but it takes time), so gfx vendors do not allocate big resources to support it, so the developer-experience is suboptimal, the classic chicken-egg problem.
