Issue descriptionUserAgent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/67.0.3396.99 Safari/537.36 Steps to reproduce the problem: 1. Monitor your machines cpu usage (i use top) 2. Open chrome. Load cnn.com into a tab 3. On my machine, as long as cnn.com is the active tab, a cpu process for chrome will use 25-35% of a cpu 4. Now, with the cnn.com tab still active, open devtools. 5. As long as the cnn.com tab is active/selected and devtools is open, two chrome processes will spike, with one at or above 100% and a second in a slightly lower range. The fan on my machine starts to hum. 6. If I try to navigate the devtools window tabs (like Network, Source, etc), the window is unresponsive. The tabs may switch, but content is not displayed. 7. Eventually (within 2 minutes or so of no user interaction), the browser opens an error window: Page Unresponsive You can wait for it to become responsive or exit the page. DevTools - www.cnn.com/ Exit Page | Wait 8. At any time, I can return my machine to normal cpu usage by simply selecting a different tab in my browser (one that has a simple page, like example.com) or by closing the devtools window. What is the expected behavior? Using devtools on cnn.com should not freeze the devtools interface and cause the host machine to dedicate 100% of two cpu's to chrome processes. What went wrong? Cnn.com is a bit of a cpu hog on its own. For some reason, the combination of cnn and devtools causes devtools to become unresponsive. Did this work before?

I tried with no extensions installed and have not changed any default chrome flags but still experience the problem. Please try your test again, but: 1. Do not use the Chrome task manager for CPU monitoring. Instead, open a terminal window and use Top to monitor CPU usage. 2. Open Devtools in an undocked (new window) window. I noticed in trying to duplicate your test that the CPU spike is much less severe (and the interface does not freeze) when devtools is docked as it was in your test. Watch the cpu usage and wait for a minute or two. You should experience the problem unless this is only related to my earlier Ubuntu build or my machine. David

Thanks for the report. I'm also unable to reproduce this bug. Unfortunately, there's not much we can do. If DevTools is responsive for a while before freezing up, could you please check for errors in the DevTools on DevTools console?
