Improvements

- Fixed the issue that a video scale above 100% crops the video by the player's boundaries at pageload

Improvements

New
- The "Video: size" setting has been split into a size setting per view (small, theater, fullscreen)

- Display a warning when the ambient light cannot not be displayed because the video is DRM protected by YouTube. (This happens on movies you have to buy.)

Improvements
- Unlinked the "Video: size" and "Bar detection: Fill video to removed bars" settings to make filling to a user-specified video size available
- Offloading the bar detection and Energy saver features to a separate thread/process even when the TrustedHTML api is required (Which was introduced by YouTube's 31 July 2024 update.)

- Has now the ability to ignore elements inside bars which are not edges
- Improved detection speed

(Vivaldi blocks downloads of blob URLs)

- The default value for the "Quality > Synchronization" setting has been changed to "Decoded" to workaround a bug in Firefox that limits the framerate to 24fps. Related bugreport: https://bugzilla.mozilla.org/show_bug.cgi?id=1935256

Fixes

New:
- New advanced setting: Ambient light > Fixed position

Changes:

- The setting "Page content > Buttons & boxes background opacity" can from now on also be set to a negative value. This makes it possible to have black background colors in the buttons and boxes on a white themed page and vice versa.

Improvements:
- General page rendering performance improvements. A degraded scrolling experience was most notable on low-end devices, but this was also be noticeable on high-end devices with high refresh rate monitors after you had scrolled through 300+ comments. Some interactions where these improvements will be noticeable are: Scrolling and resizing the webpage; Scrolling through lists; Switching between normal, theater and fullscreen views; Scrubbing through the video timeline; Opening/closing the side menu
- Reduced the CPU and GPU usage when the settings "Ambient light > Blur" and "Ambient light > Spread" are both set to 0%
- Reduced the CPU and GPU usage when the video itself fills the screen in fullscreen view

Fixed:
- The automatic page theme switch triggered a refresh of the YouTube watch page because YouTube had redesigned their webpage

- Maximize the "Sync video with ambient light" video overlay to the resolution on screen

Fixes:
- Prevent an incorrectly scaled video in YouTube's miniplayer after black bars were removed on the watch page

- Restyled the shadows on the buttons below the video player (YouTube redesigned those elements)
- Disable "Synchronized video with ambient light" when the video is in fullscreen and filling the screen

New:
- Setting: Quality > Energy saver (Limits the framerate on video's with an (almost) static image)

Improvements:
