1740679 - 'about:webrtc' page is glitching when opened.

Status: NEW

(Core :: WebRTC, defect, P3)

Description

[Monica Chiorean]

Attachment: Screenshot_Fixed.gif

Affected versions

• Beta 95.0b5 (64-bit)

Affected platforms

• Win 10 x64
• macOS 10.13
• Ubuntu 20.04 x64

Steps to reproduce

1. Open any WebRTC application, e.g. v3demo.mediasoup.org in 2 tabs.
2. Open about:webrtc to monitor WebRTC metrics.
3. Click on Show details.
4. Scroll down the page.
5. Observe the scroll bar and whole page.

Expected result

• Webrtc page should not glitch.

Actual result

• Page is glitching (loading too many times - when show details is pressed to view more details).

Suggested Severity
S3, since it is a display issue.
Issue is not reproducing on: OLD->Nightly 92.0a1 (2021-07-23) and Latest->Nightly 96.0a1 (20211110214946) (64-bit).
It seems to reproduce mostly on Beta versions not on Nightly builds.

Regression range

• I will add one as soon as possible.

Additional notes

• This is logged based on comment 5 and 6 from bug 1721963.

[BugBot [:suhaib / :marco/ :calixte]]

The Bugbug bot thinks this bug should belong to the 'Core::WebRTC' component, and is moving the bug to that component. Please revert this change in case you think the bot is wrong.

Setting tracking flags based on description, may have been fixed as part of the libwebrtc update?

I was not able to generate a regression range, but the issue seems to reproduce as long as RTP Stats are online generated. Thank you.

Removing keyword as this can not be done on mozregression using Beta version. Also issue does not seem to reproduce on latest Beta 108.0b2 on Win10.
