Shot of Google Maps with black sidebar.

Loading maps.google.com initially renders the sidebar fine but it flashes to black after a second. Search field seems to work, but content renders black again. Tried loading without 1Blocker, same result. Only other plugin is 1Password. 10.13.6, STP 63. This has been occurring for the last few STP builds. See attached screen shot.

Supposedly fixed by r235843.
Comment 4 Simon Fraser (smfr) 2018-10-31 13:28:10 PDT
But that was over a month ago, and we still have reports coming from more recent STP builds.
Comment 5 Jon 2018-10-31 14:08:47 PDT
Seems fixed in STP 68, at least for me.
Comment 6 Jon 2018-10-31 14:09:43 PDT
That would be STP 68 on 10.14.1.
Comment 7 Ryosuke Niwa 2018-11-02 03:34:44 PDT
This is definitely broken on STP68 for me. Maybe we need high sierra or MacBookPro10,1 to reproduce it?

Hm... I'm not reproducing this problem on the same machine either. It's possible this is some kind of a GPU driver bug in MacBookPro10,1.

It's not a rendering issue; the element background really is black. It's about the timing of the sidebar rolling up.

I haven't seen this in a while. I suspect the website has fixed the issue.
