Violation 'Mousedown' Handler

Hello,

I am an end user experiencing a problem with SoundCloud and not sure where to turn next for help. The reason I am here is because I have already thoroughly researched the problem, determined the cause, and am not getting any help from their support community or direct support. The problem occurs across any PC-based browser (I don't have access to a Mac or Linux machine to test), with the same results and behavior. Naturally, I have the latest versions of the browsers installed and have run tests in "safe" / "incognito" modes to eliminate addons or extensions as the culprit. I followed proper procedure at the begiing of the tests as to rebooting my machine, cycling my router, clearing caches, flushing DNS, trying alternate DNS, and even a different network with a different service provider.

If you feel so inclined, you can check out more details here: https://soundcloudcommunity.com/soun...y-feed-7363375

In a nutshell:

- When browsing SoundCloud, I eventually end up with an unacceptable delay between songs. This delay increases the more songs I play, and eventually hangs the browser ("Not Responding, Do you wish to close these tabs...?").
- Opening the console and setting the error reporting to verbose reveals that each and every delay in browsing coincides with a reported violation of "Mousedown Handler", varying from 200ms to 60,000ms+.
- You can see screenshots here: Imgur: The most awesome images on the Internet (One error singled out), Imgur: The most awesome images on the Internet (Many errors), and https://imgur.com/2jjEbub (transition from normal behavior to error).

Okay. So, actually, what I need to know is simply whether or not the 'mousedown handler' latency is due to a problem on their end, or mine. I did some independent research on this and could only find information on how to properly code this handler; nothing about the end user having problems with it that they had to troubleshoot. My gut and many years working tech support tell me that this is an issue on their end.

I've already given all of this information to SC, and their help community, with no results. I am hoping that if I have a bit more evidence on my side, I can persuade them to fix this problem.

Thanks in advance for all your help,
Matt
