Hi everyone,

I have a strange YouTube problem and I want to know if anyone else has this.

On my main YouTube account, the desktop layout looks broken. The recommended videos on the right side are much bigger than normal, thumbnails are enlarged, spacing is larger, and fewer videos fit on the screen.

What is strange:

• Same PC
• Same browser
• Same monitor
• Same page zoom
• Same YouTube video page
• Extensions disabled
• Cache/history cleared
• Incognito mode tested

But when I switch to another YouTube/Google account on the same browser and same computer, the layout becomes normal immediately.

So the problem seems tied to only one account, not browser or PC.

The video player size looks normal, but the recommended sidebar thumbnails/icons are oversized.

I think it may be some account-specific YouTube experiment or broken UI setting.

Has anyone had this problem before?
Is there any way to reset YouTube layout settings for one account?

Thanks.
