Comment # 15 on bug 1149308 from Michael Matz

FWIW, I have no hardware accell in chromium, but no stuckiness or overly high
CPU load on my system.  It's Intel hardware only, and chrome://gpu says
everything software only.  I have shared the camera and show it nearly full
screen and my CPU load as at 100%, i.e. only one CPU out of the eight I have.

So, when GTM becomes laggy it's _not_ the missing GPU hardware accelleration
in itself that causes it.  But it might of course lower the stuckiness factor
for those that exhibit it.

(FWIW, openSUSE 12.3, kernel 3.7.10-1.16, chrome 72.0.3626.96)
