Weird Blank Spaces On Youtube's Home Page

I just Opened Youtube and found this odd empty space in it

Kindly Ignore the videos I couldn’t blur it out
and also the space I marked couldn’t drow a proper square, hope you get the idea

Note: This Doesn’t happen always
just a few times

Yeah it’s known.

we hide the ad, but because of the youtube design it won’t collapse with standard cosmetic filtering.
