const { createCanvas } = require('canvas');

function renderImage() {
  const bgCanvas = createCanvas(800, 600);
  let bgCtx = bgCanvas.getContext('2d');
  bgCtx = null;
  global.gc();
}

console.log('Memory usage before:', process.memoryUsage());
renderImage()
console.log('Memory usage after:', process.memoryUsage());

The above code is a minimal code sample from a possible memory leak in my discord bot. It seems to be using anywhere between 20-40mb of memory with the .getContext() method and not giving it back. Any insight would be greatly appreciated since I am completely lost here.

I am using canvas ^2.11.2

This is the memory log:

Memory usage before: {
  rss: 35856384,
  heapTotal: 4665344,
  heapUsed: 4369736,
  external: 1323854,
  arrayBuffers: 10515
}
Memory usage after: {
  rss: 63238144,
  heapTotal: 5976064,
  heapUsed: 3500384,
  external: 1455306,
  arrayBuffers: 10475
}
