RayTK renderers are exhibiting some strange behavior in Vulkan.
The raymarchRender3d shader in some cases works fine, but in others, it will output nothing, except while parameters are being adjusted, at which point it flickers on and off.
The render2d shader also works fine in some cases. But in others the output strobes RGB, sometimes showing distorted versions of what it should be rendering and sometimes showing solid colors.
