(Core :: Web Painting, defect)

User Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:57.0) Gecko/20100101 Firefox/57.0
Build ID: 20171206182557

Steps to reproduce:

1. Install and start Firefox 57 on Windows 7
2. Go to https://www.phoronix.com/scan.php?page=home or GMail account



Actual results:

The rendering is only partially done; lots of elements are missing, though the page is completely loaded.
Hovering the mouse over those elements sometimes makes them render, sometimes not (it seems to depends on the interactivity of these elements).


Expected results:

The rendering should be correct and complete.

@repoter,

Could you attach a result of about:support here?

And, if you think this is a regression, would you try to narrow this regression down using the mozregression tool( http://mozilla.github.io/mozregression/ ) ?

After some more testing, it looks like the bug is more random than I thought: I'll re-run the bisect to see if I end up with the same result.

I've reset my profile, and it looks like I can't reproduce the issue anymore.

I'll close the issue - sorry for the noise !
