<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?).

Research direction
Start by reproducing the report on the code4rena main page with the supplied canvas element, comparing CPU usage in Chrome and under the reported conditions. Inspect the page's three.js r150 canvas behavior and document a reliable reproduction, including any graphics-card or environment differences. Done means the cause is identified or the report is narrowed with enough evidence for a follow-up.
