… any idea what this glitch is?
Need codepen example.
webgl_modifier_tessellation is potentially a good start. You just want to vary the vertex displacement along the x-axis.
Depending on how your geometry is composed, TessellateModifier is not required. The modifier just ensures there are enough faces to produce a better dissolve effect.
Just to be clear, I am not trying to create this effect. This is a glitch. I am trying to have the 3d text show up correctly, and instead it shows up like this.
