My current favorite is the vanishing scrollbars that appear for two seconds after you start scrolling. Chrome is awful with this. When I'm trying to review a couple-thousand-line PR, Chrome stutters and freezes, and the scrollbar won't show up for several seconds and then it immediately vanishes as the UI catches up with the input. Or sometimes I click on the ephemeral scrollbar but my click doesn't register until after it's vanished again. It's infuriating.
