Public bug reported:
from 'lspci':
00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core
Processor Family Integrated Graphics Controller (rev 09)
Was using DOSBox earlier and I noticed that vsync was not enabled. I
can also see vsync is not enabled while I type at the terminal wrapped
by gnome-shell (visible tearing in the cursor block as I type).
I installed CCSM and verified that "Sync to VBlank" was already enabled.
Am I missing something, or is this a bug?
