On xfce, Intel HD 4000 with DRI 3 - laptop freezes. Step to reproduce:
1) Enable DRI 3, add Option "DRI" "3" and Option "TearFree" "true" to xorg
file.
2) Reboot
3) Install virtualgl. In terminal, open glxspheres64. Open chromium, take tab
and start moving it quickly across the screen.
4) Screen freeze. Screenshot:

With "DRI" "2" system not freezes, but moving windows is delayed and there are
white color graphic artifacts from the top(its not tearing, i know this), when
you drive the cursor on the background of this video:
<a href="https://www.youtube.com/watch?v=cuXsupMuik4(watch">https://www.youtube.com/watch?v=cuXsupMuik4(watch</a> in 1080p60). With uxa
everything ok.
