Error linking program
The ♦ shader uses varying FragWorldPos, but previous shader does not write to it.
Out of resource error.

Get this error when using integrated graphics (on Windows, Linux and MacOS). Solution was to add "out vec3 FragWorldPos;" to wiggly_shader.vert

Additionally, I modified the program to compile and run on MacOS and Linux WSL with both performing equally horrendously on Integrated graphics (UHD Graphics 630). Worked perfectly fine (high fps) when compiling for Windows using integrated Graphics... Very odd.
