<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?).

Faced similar issue sometimes.
Fixed by turning hardware acceleration on in the browser (chrome). Shows up on Brave as well with hardware acc. off, but not on firefox.
