Guessing now but is it trying to stream anything to a phone, or running
OBS for video editing, anything that might make it go 'crikey, let's
throw everything at the graphics to be ready for X'?
Lots of things can be installed that are ready to stream video to a
nearby device from the Mac. I can't remember the names of any of them (I
think VLC has one though?)
For more troubleshooting, I'd see if a different account on the same
machine has the same thing. If not, it's something you have running in
the background (even if it does it might be installed for all users).
Cheers,
Jason

Thanks, Jason.
I'll have a peruse of that article.
The background image is just a stock Apple wallpaper (not one of the
animated or varying ones but just a nice colour!)
Not sure what could be demanding graphics work. Will have a ponder and
see
what's what. Just now it fired up for literally 3 seconds and then
stopped
(and never tends to get going again, so it's something on startup).
And I'm running 15.7.2.

Do you have a high res background image on your desktop? *Something*
is
demanding graphics work. Anything in Accessibility about contrast
etc. What
OS are you running?

Hello everyone
Just a small thing really, but my MBP is a faithful workhorse nearly
7
years young.
Only thing I've noticed lately is whenever I boot (and/or wake from
sleep)
the fans get very loud as it gets very hot for the first 5mins or so.
It
then settles down quite happily.
I've attached a screen grab of Activity Monitor if there's any
gremlins
lurking there anybody can identify?
Thanks
Adam
