Xfinity Stream Portal taking a lot of cpu power

It's due to the UI and need to lower the graphics or whatever is going on with that overlay! 
When the video is Paused and the UI hides and I press play then the video plays perfectly and in 4k at 60fps but the moment the mouse hovers on the browser and that nasty UI shows up then my PC starts to scream and cpu spikes and the fans  goes crazy! It's happens on every browser I installed From Firefox, Chrome, Edge even Brave, Please can you guys fix that!?

Good afternoon @user_hzzdph. I can forward your feedback to our XFINITY Stream group for review. When you are using a browser, are you running into any other issues?

Good afternoom XfinityRaf
Yes definitely! That's the only Issue about the UI even on hardware acceleration on the browser option it's also happening with Youtube and probably the culprit could be Windows 11 or nowadays AI

Thanks for confirming @user_hzzdph! Since you’re seeing similar behavior with YouTube as well, it may not be isolated to the Xfinity Stream Portal. For the Stream Portal specifically, have you already tried clearing your browser cache and restarting the browser to see if there’s any change in the CPU usage when the controls appear?

Hi, yes I did the cleaning, restarted and still, even upgraded my RTX4060ti graphics card that should overkill this situation and the video is also spiking it! This started to happen after the world cup and I thought it was a browser update but then if I downgrade your player is not compatible and I have to stay on the updated version in order for Xfinity Stream portalto play!

After our last conversation all of a sudden it started to work, I don't know if it was Nvidia with an update or my browser but now there is a new issue
So I'm paying almost $300 a month just to get kicked out of the browser, I log in and kicked out? This is a travesty! 😡😡😡😡😡
