I can reproduce this bug on Linux without ublock origin. The content start shaking after I shrink the browser's width to around 1400px.

In the screencast, the devtool panel shows that the site's script is changed CSS properties for different elements, resulting the layout instability.

I've emailed them about this bug via https://sciencex.com/help/feedback/

Well but do we know why their script now is changing the values back and forth and why it doesn't happen on other browsers?
