Text component has memory leak on M1 Silicon

[hpaul]

Bug

while using react-native-svg library for building graphics in a macOS app, I encountered a problem regarding performance, or a memory leak, don't know how I should call it.

When iterating over an array and mapping values into a component, the application frozens and memory usage goes up-high (>4 gb). I've tried to overcome this, generating the svg using the component, independent component for text, but further it proved that the problem comes from a lower-lever code.

The snippet :

<Svg width={width} height={height}>
  <G y={10}>
    <Path d={`${this.linePath}`} fill="none" stroke="white" strokeWidth="1.5" strokeMiterlimit="20" />
  </G>
  <G y={40}>
    {this.xTicks.map((tick, i) => (
      <G key={i}>
        <Line x1={tick.x} x2={tick.x} y1={tick.y} y2={tick.y + 5} stroke="grey" />
        <SVGText originX={tick.x} originY={tick.y + 20} fill="pink" textAnchor="middle" fontSize={8}>
          {tick.label}
        </SVGText>
      </G>
    ))}
  </G>
</Svg>

As I don't have great skills in low-level languages and don't know how react-native-svg internally works and I'm using a relative new system (M1) together with NSPopover in system tray, I guess it's relatively a unique problem.

How do you think I can debug this?
