Ask HN: Is the YouTube GUI slower during ads?

In general i refuse to watch advertisements. Luckily there are various options to open videos without them.

This makes the occasional miss-click on a YouTube video very annoying, which brings me to my question.

Is it just me, or does YouTube slow down its interface when an ad is playing?

On my android phone just now, the picture wouldn't move to landscape, an overlay music player wouldn't capture the audio player when i pressed start, and the pause button on the Ad had a 3 second delay before taking effect.

I've suspected similar dark patterns on my desktop, but it might be my imagination and the budget phone I'm using.

Anyone have a similar experience?
