Problem still not solved in version: 101.0.4843.25

The redesigned Video Popout doesn’t look appealing or useful. The rounded corners reduce video details in the corners. When you hover the mouse pointer over the popout, an unattractive gray overlay appears. The play/pause button is now in the middle instead of the bottom left corner. Additionally, the volume button is located at the top left, and the vertical volume bar only appears when you hover over the volume icon. The inverted volume bar (with 0% at the top and 100% at the bottom) is confusing. Furthermore, there’s no video timecode. Overall, this redesign isn’t helpful for users who frequently use the video pop-out feature, and it feels like a downgrade compared to the old design. Please reconsider and keep the old Video Popout design.

I've encountered several issues with Opera GX after the recent update 115.0.5322.142:

O Menu: The O menu takes up too much space, hiding the "Exit button" below "Update and Recovery button".

Bookmarking: when bookmarking webpage, The Bookmark popup UI takes a long time to load and glitches. When it finally loads, it displays a half-moon icon glitch and doesn't load properly.

Thumbnails: Bookmark thumbnails now appear as title strips rather than proper thumbnails.

The overall user experience has deteriorated significantly. For context, I'm using a 15.5-inch laptop with an i3 processor, 8GB RAM, and a 500GB SSD.
