Hi!
New x11-drivers/nvidia-drivers-378.13 cause non-stop 100% usage one (random) core my AMD FX-8320 while browsing Firefox-51 with use-flag +hwaccel. Firefox-51 with -hwaccel does not have this problem, but no HW acceleration and fonts in FF is ugly. With x11-drivers/nvidia-drivers-375.39 and FF-51 +hwaccel there is no problem.

My videocard - GTX 1050.

What is using that CPU time?

It begin from start FF-51.

Almost always from the start FF or you need to open one or two tabs to it began.
The same behavior with a clean profile FF. E10s is turned on.

As the useflag description says you are force enabling hardware acceleration, we do not have time to track bugs from a binary driver, if you feel you have found a legitimate bug please fill with upstream.

No, please, what _process_ is using up that CPU time?

The main process - firefox, not /usr/lib64/firefox/plugin-container...
