@Pathduck this unfortunately didn't work for me. i put the custom CSS text into a new note on my computer's notepad app, named it with the .css file extension so it would save as one (it was trying to save as .txt; i checked my files after saving it to confirm that it did save as a .css file), and put it into a folder before importing that folder into the settings shown in the modding guide you linked. all it does is make the fullscreen UI flicker a little. it's still visible and still stays for the same amount of time as it did before. i want it gone because i'm taking interview stills from videos and the pop-up makes things...a lot less efficient, to say the least.

@bryk That fixed it! Thank you.

Hello community, I've been using Vivaldi for 6+ months. I like it very much, it has been very productive at work on Windows, however on my personal Mac, I've been having significant issues streaming any type of video on Vivaldi (ie on YouTube). When I do so, my CPU load goes through the roof and computer stops responding at times (fans at full blast etc.) I've used a CLI tool called htop to check my CPU load streaming a video on Vivaldi and Google Chrome and its radically different. On Chrome, I practically never go above a load of 5. [image: 1752526820125-screenshot-2025-07-14-at-22.56.22.jpg] While in Vivaldi, I'm well into the 6. [image: 1752526914386-screenshot-2025-07-14-at-22.54.34.jpg] Even recorded a CPU load 9 when the computer was in complete panic after I was able to regain partial control and closed the tab with YouTube on it. [image: 1752527032485-screenshot-2025-07-14-at-22.44.42.jpg] Is there sometimes that I can to prevent the computer from losing it when streaming on simple HD video on YouTube?

@LittleBuddha have you tried disabling Use Tab Zoom option? It fixed for me. The behavior I was having was on all tabs it was defaulting to the Default Webpage Zoom setting, but disabling that option made it work as expected.

@sirrichard The thread is not tagged, so there are no plans yet to implement it. Since there is an extension to do this, and only 43 upvotes after five years, there is not much incentive to do it. Try the extension, and see if it works for your needs.
