The bare row becomes a single line — title truncating into the space
left, then channel, badges, meta and the actions each holding a fixed
column — and it drops the 896px reading cap, since with the actions
right-aligned there is no gap for the extra width to stretch. The
actions get a reserved slot: the reset button only exists for videos
with watch state, so without one the meta sat 32px further right on
some rows than others.
Rows and tiles get a permanent container instead of a hover-only fill.
They were transparent at rest and painted an opaque bg on hover, so
running the pointer down the list kept covering and re-revealing the
ambient backdrop — which reads as the background flickering.
Card actions now sit on the bottom edge rather than wherever the title
ends, and the small thumbnails carry icon-only controls: the labelled
Continue / Restart are sized for a card's image and were clipped at
176px.
