Abnormally high CPU usage from canvas element?

Reported at https://discord.com/channels/810916927919620096/810931711609143326/1089772242361127033:

<canvas id="background" data-engine="three.js r150" width="807" height="170" style="width: 807px; height: 170px;"></canvas>

Above code is from code4rena main page , someone need to check for issues in this piece of code that caused my computer to freeze by using 100% of its CPU resources every single time .

I do not see similar testing in Chrome myself, but could be something to review or at least keep an ear out for if other similar reports come in to corroborate or provide more clues as to the situations that could cause this (e.g. is it graphics-card dependent?).

Comece reproduzindo o relato na página principal do code4rena com o elemento canvas fornecido, comparando o uso da CPU no Chrome e nas condições relatadas. Inspecione o comportamento do canvas do three.js r150 da página e documente uma reprodução confiável, incluindo quaisquer diferenças de placa gráfica ou ambiente. Considera-se concluído quando a causa for identificada ou quando o relato for delimitado com evidências suficientes para um acompanhamento.
