Upgrade to xf86-video-intel-1:2.99.917+688+g49daf5d-1 slow down ST3

Upgrade to xf86-video-intel-1:2.99.917+688+g49daf5d-1 intel video driver slows down Sublime Text 3.
Downgrade to previous version solves the problem.

Also this upgrade breaks my kde session. KWin crashes all the time. Downgrade helped me too.

Also Cairo library can be the reason, I'm not sure now

It's possibly related to the switch to DRI3 as the default Direct Rendering Infrastructure. I was seeing remarkably laggy rendering on an external monitor using intel-virtual-output until I switched back to DRI2. (Strangely, performance was only bad when the external monitor was on and my laptop screen was off. Things were fine when both were on.) You can revert to DRI2 by adding the following section to /etc/X11/xorg.conf.d/20-intel.conf

Section "Device"
    Identifier  "Intel Graphics"
    Driver      "intel"
    Option      "DRI" "2"            # DRI3 is now default
    #Option     "AccelMethod"  "sna" # default
    #Option     "AccelMethod"  "uxa" # fallback
EndSection

Have you tried switching back to DRI 2? That fixed some problems for me.

[EDIT] oops, loh said it all, sorry

It created different problem for me with compiz 8.xx

UPDATE:

now I'm using modesetting, xf86-video-modesetting package in xorg-server.
might solve your problem too. intel seem too be buggy.

Intel xf86 driver is recently breaking 1) Firefox fullscreen videos, 2) system suspend (new entry)

Switching to modesetting solves all problems (but few glitches and a bit slower).

I have been using xf86-video-intel + TearFree on my Ivy Bridge PC for ages. However after recent updates it had become very buggy with terminal screens frequently blanking or not updating. I tried both DRI2 and DRI3. So I gave up and switched to modesetting a couple of weeks ago and no problems since. GNOME overview animation is still not quite as smooth however as f86-video-intel + TearFree + DRI2 was.
