"Digital" artifacts with harmonic intervals in BIAS FX 2

ruok

Playing harmonic intervals is giving me these really low-quality distorted sounds. Here is an example:

I am getting those coarse, "digital" sounding tones from any distorted sounds. I checked my signal and it's not clipping at my interface level. My DAW isn't showing any clipping either. It's more noticeable in the higher ranges. Single notes seem to sound fine, i.e. they don't have that lo-fi quality to them. I tried lowering the volume on my guitar, using the tone knob on my guitar, adjusting the gain on my interface (from lowest to highest). Nothing changed. Clean tones don't have that or at least it's not noticeable.

I am running my guitar (Squier Contemporary Telecaster) directly into an USB audio interface (Focusrite Scarlet Solo 3rd Gen).

Is there anything else I can do to remedy this? What's to blame for this? Is it my guitar (pickups), my audio interface or something else? Is anyone else experiencing this too?
