[Bugmon [:jkratzer for issues]]

Unable to reproduce bug 1865713 using build mozilla-central 20231119091854-c3021f5ece18. Without a baseline, bugmon is unable to analyze this bug.
Removing bugmon keyword as no further action possible. Please review the bug and re-add the keyword for further analysis.

Comment 4

[Jason Kratzer [:jkratzer]]

I'm not sure why bugmon was unable to reproduce this issue. I'll run the bisection locally.

Comment 5

[Jason Kratzer [:jkratzer]]

This bisects back further than a year so we're unable to produce a bisection range for it.

Comment 6

[Bob Hood [:bhood]]

WebGPU is unreleased tech, so I'm reducing the Severity to S3 to remove it from org tracking.
