Using the per-revision bisect providing the bisect results,
Good build: 57.0.2987.129 (Revision: 444944).
Bad build: 58.0.2989.0 (Revision: 445281).

You are probably looking for a change made after 445268 (known good), but no lat
er than 445269 (first known bad).

CHANGELOG URL:

The script might not always return single CL as suspect as some perf builds might get missing due to failure.

From the CL above, assigning the issue to the concern owner 

@alph- Could you please check whether this is caused with respect to your change, if not please help us in assigning it to the right owner.

Thanks!

It has nothing to do with the patch. Wrong bisect?

Summary: Blue line is not seen under 'Layers' section tab when it is selected. (was: Regression : Blue line is not seen under 'Layers' section tab when it is selected.)
Correction :
This is a non-regression issue, seen from M-57 series as 'Layers' option appears from build # 57.0.2928.0

Note : Issue is seen only when 'Layers' tab is added.
