google chrome – Overlapping text entry cursor over Arch Liunux

When I use an online latex editor, the text cursor is displayed a few characters to the right of the actual position of the cursor, the text being inserted by typing it.

It's very annoying and makes the work impossible.

This problem only affects the following pages and only my Arch Linux installation. It appears in Google Chrome and Firefox. It works normally when I use Windows.

Any ideas on a fix?
