List view broken by YouTube update

[NeverGameStar]

There seems to have been a YouTube update a few hours ago which broke the display of videos in the list view:

They're now displayed in enormous / full-width size.

Same issue here. I can shrink things down a bit by adjusting the "max list width" setting. But yeah, whatever youtube did broke things.

Yeah, thumbnails are massive now lol. Still can't believe Youtube just got rid of the list view in the first place.

I've analyzed the issue: YouTube recently changed several CSS class names (switching to a camelCase format), which broke the selectors for this script.

I have submitted a Pull Request with a fix that supports both the old and new class names.

For those who need an immediate fix:
I've created a Gist with the patched userscript. You can copy-paste it into your userscript manager until the official one is fixed:
Fixed for YouTube update April 2026
