Performance tools not showing stack info

[Roxin Cernica]

Hi,

Does any one else have this problem:

After profiling, there's no stack information - just XHR Load, Function call ... and that's it - no info about the individual functions being called.

Sometimes if I do CPU throttling the stack shows up, most often it does not. Any website.

Happens with regular Chrome/Beta/Canary - Windows 10 latest updates - ryzen 7 3700x cpu.

Any thoughts?

Thanks.

Do you have specific steps to reproduce? E.g. which web site you are profiling.

Cheers,

Yang

Hi, 

It unfortunately happens on any website ... and steps to reproduce it’s just starting a performance session, doing some actions and stopping it.

In this particular case it’s the CNN website.

Thanks

Hi Roxin,

do you have "Disable JavaScript samples" checked by a chance? (click the settings cog in the top right corner to expand timeline options bar at the top).

Best regards,

Andrey.

Hi Andrey,

No - it's not checked. Also: all chrome versions behave the same way (beta / canary).

I tried another thing - I downloaded MS Edge based on Chromium - and I have the exact same behavior.

Firefox however shows the proper stack ... but it's quite crappy compared to Chrome :)

Thanks for taking an interest in this.

Best regards,

Roxin

Hello.

It doesn't works for me ONLY when debugging an Android device.

I've tested the same page in:

- osx + Chrome 80.0.3987.163 (Official Build) (64-bit) 
- osx + Chrome 84.0.4122.0 (Official Build) canary (64-bit)

- ubuntu + Chrome (cannot see the version now)

Using this devices in each OS:

- Honor 9 + Chrome 81.0.4044.111 (Android 9)
- Samsung Galaxy A8 + Chrome 81.0.4044.111 (Android 9)

The graph in Chrome Desktop works well using both sampling modes:

But in Android, the "Disable Javascript Samples" does nothing:

Has someone this issue when remote debugging is active??

I have this problem too. Maybe this never worked when debugging Android devices???

[TIME HAX]

For me, this started occurring after a Chrome update, although I don't exactly remember which version. There are no details about the performance metrics of individual functions/methods by name, only totals through "Function Call", which is rarely helpful. For me, this happens on desktop web-apps, it doesn't require profiling an Android app to reproduce it. LMK if you figured out a solution.

[Chris Geiersbach]

I'm seeing this too. I've ensured I have the "Disable JavaScript samples" checkbox unchecked, but I don't get any call stack information.

I have chrome 80.0.3987.163 on Pop!_OS Linux

[Chris Geiersbach]

Note, I've downloaded the beta version 83.0.4103.44 and it seems to be fixed
