The website https://duckdice.io/decoy/staking is broken or there's something really un optimized there. If I have this site open on another monitor and let's say youtube on the other, YouTube will lag and buffer videos until it comes to an complete hault. The lagging stops immediately if I close the tab. This happens on multiple browsers and on multiple different pc's.
It also lags out my phone (Honor 70), if I have this site open and I swipe down to see my notifications my fps drops about 1/4'th of the regular 120.
Maybe it's the falling coins animation?
