New features in Angular10: Improvements in canvas image rendering efficiency

After updating Angular from version 9.0 to 10.1, I encountered an issue where the canvas image is displaying out of order. Whenever I click on the Status Tab, the image becomes disorderly.

Interestingly, the problem seems to be present only in Angular 10.1 and not in Angular 9.

Here's a snippet of my HTML code:

<canvas [id]='canvasId'></canvas>

In my TypeScript file:

this.canvas = document.getElementById(this.canvasId) as any;

I suspect there might be two canvases being rendered, with the old canvas still lingering somewhere. Can anyone provide me with some insights on how to resolve this?

Answer №1

prop.solution:

let graphDiv = document.getElementById('graphDiv');
graphDiv.innerHTML = '';
graphDiv.append('<canvas id="graphView"><canvas>');


<div id="graphDiv">
   <canvas id="graphView"></canvas>
</div>

I cleared and recreated the canvas inside the div, which worked perfectly. But I'm still puzzled by the presence of two canvases.
