Regression range

Additional notes

  • I reproduce this issue only on one machine
  • Recommended severity: s3
Attached file about_support.txt
Has Regression Range: --- → yes
Has STR: --- → yes

From the first range, bug 1284877 seems relevant, and from the second range, bug 1559011 seems relevant. Maybe bug 1315737 opened up access to some features. Either way, I expect media can better evaluate these pushlogs. There did not seem to be anything graphics that is relevant (but it is a long list and I could be wrong).

Component: Graphics → WebRTC: Audio/Video

At S3 and without a clear fix, we're not going to be taking this in 78.

Hi Anca. I'm not able to repro on my Windows 10 box. Does it happen for you here?

Flags: needinfo?(anca.soncutean)

The first regression range is too old to matter. Bug 1559011 might be relevant. Dan WDYT?

Flags: needinfo?(dminor)

Apparently I can no longer reproduce it myself with your link or the one used when I was filling this issue on the latest Beta/Nightly builds. I will be looking more into it next week before mark it as worksforme, maybe it is some "trigger" that I am missing.

That is certainly possible, but I thought Chrome windows could not be shared at all before Bug 1559011 landed.

Marking P3 until we get confirmation from Anca that it is still reproducible.

Severity: -- → S3
Priority: -- → P3

I can no longer reproduce this issue, not on the latest Nightly/Beta versions, nor on the ones available at the time of submitting this problem (tried with Windows 7, Windows 8.1, and two test machines with Windows 10). I’ve tried to recreate the context in which I’ve triggered the issue initially (as far as I could remember), but with no payoff. Probably, there is indeed a particular “trigger” for this issue, but since I can’t determine the “culprit”, therefore it no longer happens on my end, I will mark the bug as Worksforme. Feel free to reopen it if the case!
