evolution and Xorg bomb after these days xorg-x11-drv-intel updates?

[Gianluca Cecchi]

Hello,
noticing since yesterday that when I start evolution my laptop
temperature rapidly jumps from 40-45 degrees to 70-75 and I'm forced
to stop it.
When starting it, without doing anything I see this "top" output
sorted by %cpu that explains the jump:

Normally and if I stop evolution, I then get again

So I suspect xorg-x11-drv-intel as my system is an Asus U36SD with
Intel and nVidia (that is disabled during above tests)
But it seems to happen with evolution only... I don't know which kind
of interaction could be in place.
00:02.0 VGA compatible controller: Intel Corporation 2nd Generation
Core Processor Family Integrated Graphics Controller (rev 09) (prog-if
00 [VGA controller])
01:00.0 VGA compatible controller: nVidia Corporation Device 1050 (rev
ff) (prog-if ff)

Anyone else experiencing this and/or having a bugzilla id already open
to post to?
Or I'm going to open a new one...

Thanks in advance,
Gianluca
