TB 45.6.0 forces High Performance GPU on 2010 Macbook Pro
Thunderbird unnecessarily requires high performance GPU instead of integrated IntelHD which causes a major battery drain.
Restarting and disabling Add-ons had no effect Other attempts to disable certain graphics functions has also not yielded a change in requiring high performance graphics to be enabled.
Thunderbird is an email client, this certainly is not required. Other applications have found work arounds for this particular issue including firefox.

Thunderbird tends to follow what Firefox does.
Does the same thing happen with Firefox?
Hey Wayne,
Thanks for the response!
The screenshot I attached shows Firefox behaving in the process list. FF does not require high performance graphics kinda odd that TB does...
Happy New Years, OC
tried turning off the hardware acceleration in preferences?

Hey Matt thanks for the reply,
Turning off hardware acceleration has no effect...
I have been very thorough in attempting several config editor settings as well...
It seems it's a bug unique to this particular model, that may have re-surfaced... OC

OPk so theyOclair said
This is a bug and they closed the issue... https://bugzilla.mozilla.org/show_bug.cgi?id=1329199
My reading of the bug indicates that the choice of GPU is an OS or driver issue, not one for Thunderbird.
there is https://bugzilla.mozilla.org/show_bug.cgi?id=693852 but toggling the hardware acceleration setting (the hidden prefs in the body of the bug) appears to fix that.
