Hi, welcome.

Timely. Someone else asked about the exact same thing ~a month ago. Check
the archives for details, but basically: this happens in glsl shaders, I
would recommend the GLGridLeaper* ones since that renderer is the best one.
But, as far as I'm aware that still requires you have a newish NVIDIA card
and Linux/Windows, still.

HTH,
