Running glsl code to rgb led matrix

I want to run glsl code in my 64x64 rgb led matrix. I’ve tried the rpi-rgbledmatrix-glsl but doesn’t seems to properly map the graphics:

I’m using the same parameters that I use to run demos of with rpi-rgb-led-matrix, where mapping occurs perfectly.

I’m wondering if there’s a better way to run shaders using the original rpi-rgb-led-matrix lib.

Just to update this post: I managed to solve the problem using the width and height parameters from the library, but it was also necessary to define a chain as if they were two screens. I’m sharing the result with you all and the link to the rpi-rgbledmatrix-glsl, in case anyone else is willing to test it.
