Hide fullscreen “More Videos” grid & vignette; keep scroll-wheel volume. Prevent tick-4/7 jiggle without forcing visibility. V-key manual hide. Hide interactive overlay in fullscreen. Allow normal autohide in FS and windowed modes.
(Note: This script is designed to work alongside the 'Enhancer for YouTube' browser extension or any extension with a similar functionality.
It is primarily CSS-based, but has a lightweight JavaScript helper to stabilize fullscreen control visibility. Without it, users were encountering issues with progress bar and video controls visibility.)
Recently, Google has once again added a new feature to YouTube that no-one asked for: when using the scroll wheel while the player is in fullscreen mode, it causes a video suggestion overlay to appear, obscuring the entire screen. This script removes that ”More Videos (V)” overlay and its dark vignette background, restoring a clean viewing experience while keeping Enhancer for YouTube’s scroll wheel volume feature fully functional while in fullscreen mode. This script is mostly CSS, so no slowdown and no interference with video player controls. Without it, the volume scroll feature of these extensions is functional, but bugged and overall cumbersome to use. If you're like me and find this new overlay feature to be frustrating and intrusive since there is of course no option to disable it (go figure), hopefully this will do the trick for you.
Features:
• Removes the fullscreen “More Videos” grid / related-video thumbnails.
• Disables the vignette / dark gradient overlay at the bottom of the screen.
• Now, pressing ”V” while in fullscreen will toggle a 'minimalist' mode — all UI elements (progress bar, buttons, overlays) hide completely until you press V again or the F / Escape key to exit fullscreen. This is a side-effect of the grid removal and is intentionally left as a bonus feature.
• Keeps scroll-wheel volume adjustments (via Enhancer for YouTube or similar).
• Lightweight — CSS heavy; little JavaScript included for QoL.
• Compatible with Firefox, Chrome, Edge (Tampermonkey or Stylus).

Known Bugs in 1.3.6
The video UI will vanish after scrolling down 4 ticks, and will reappear after scrolling up 4 ticks - title still reappears when scrolling up 4 ticks while in 'minimalist mode,' but thankfully disappears on its own after a couple of seconds. I had this fixed but of course YouTube is always changing things on the backend so it broke again. It's not too bad to work around though; try scrolling a bit lower than the volume level you want it to be at, then scroll back up 4 ticks, and the video UI will re-appear. It isn't elegant, but I cannot for the life of me seem to figure this one out for the time being.
