DevTools hang w/ heavy canvas image processing & websocket

[Alan Moore]

We are using a canvas element to display raw/uncompressed rgba video images (1/4 VGA size) received over a web socket connection.

It works fairly well at about 24fps but we suspect our app might be causing memory or resource leaks. However, we cannot use DevTools to debug the app because it hangs whenever we open it.

The only memory related debugging we can do is using the Chrome Task Manager which gives us an overall picture of what is going on with the memory but it is hard to pinpoint the problem w/o DevTools.

Are there any settings we can tweak to allow us to use DevTools in this use case?

We need to fix that for you. Did you try clean profile? You'll have to either share a reduced test case in a bug at crbug.com/new or provide me with the way to open your app privately.

Regards

Pavel

I can't send you our server code because it is running on an embedded system and you would have no way to run it :-(

If I know what kind of server you are/can run I can create a minimal test case for you that works on your server. I can certainly send you the client code as it is super simple... but you'll really need a server to handle the web socket processing to push the images to the client.
