Description

I've noticed some pretty bad jitter when simply scrolling through recent releases, it appears as if the list items below the currently hovered item are resized and when moving mouse up and down somewhat fast (normal usage) it causes a jitter. Not sure how to include videos on github issues but I could include one if someone tells me the proper way.

Research direction

Start by reproducing the jitter on the recent releases list while moving the pointer up and down, then inspect the list item's hover rendering and sizing behavior. Done means the items below the hovered entry no longer resize or visibly jitter during normal mouse movement.
