[Linux-28.1.2][v1.6.0-beta3] Weird pattern in radial bars #36

Using the following settings (most of while don't really matter, I think):

Normalize Volume
Bars 1-1-0 (You could say it's basically the Curve mode)
700x700
Logarithmic Frequency Scale
Radial-Inverted
20% deadzone
90% Radial Arc
Rounded Caps
Auto FFT Size
Hann - None - Lanczos - None
30-17500 Hz
-65 - 0 dBFS

Of course setting the mode to Curve removes the patterns...

Yeah, if you use bars that small it's going to artifact. There's not much that can reasonably be done about it since it's a product of floating point error and aliasing from trying to render primitives with sub-pixel precision.
