@wkorman : Could you please help to reassign if your change is not the cause for this change.

My change only affects bounds of SVG text drawing, and so is unlikely to affect a line.  The changelog above includes WebGL rolls, a Skia roll, and a couple of other changes that could be culprit.

We should bisect within that change log. I'm OOO til Mon but can look then.

@mnikam are you able to repro this issue with latest Canary, or M55 Beta? I can repro, I think, with Linux Chrome 54.0.2840.90 but not with 56.0.2906.0.

So, if it is indeed already fixed, we could either bisect to find fixing change or close as WontFix and wait for M55/56 to ship.

With response to comment #3 :
Rechecked the above issue with latest canary chrome version 56.0.2915.0 on Mac (10.11.6) and the issue is still reproducible.
Kindly refer the attached screen cast for reference.

Just to update:

Still able to reproduce the issue on mac 10.11.6 chrome version 57.0.2931.0

wkorman@, Could you please take a look

This is such a minor, transient problem that I can't see us choosing to invest time in fixing it (relative to other tasks on our plate).
