Chrome/Edge runs slow in F12 developers tools

Question

Has anyone else seen F12 developers tool RUN SLOW, Very SLOW on Chrome/Microsoft Edge?

I tried it on FireFox and everything works fine when using F12.

Chrome version: 81.0.4044.129 Microsoft Edge version: Version 81.0.416.68 (Official build) (64-bit)

I reported it via chromium bug report. Just curious if anyone else is seeing this.

I removed a couple of extension and it still does it.

Answer 1

My co-worker figured it out.

I needed to go to Options for F12 and check "Disable async stack traces".

Once that is checked, F12 developers tool works fine and there is log lag!

Thanks Brad!
