Default System become super laggy after suspend/resume while running hwacc Opera

If I run the Opera browser with hardware acceleration support enabled, then suspend and resume my computer,
my system will become super laggy for a while.

If I then switch to a vconsole or another workspace and back, things back to normal.
Or if I disable 'Sync to VBlank' in nvidia-settings, the time it takes to recover is shortened.

There is nothing special in dmesg log or Xorg.log

System info:
OS: archlinux 64bit
Opera version: all versions that support hardware acceleration.
GPU: GT420M
Driver version: 290.10
Kernel version: 3.1.5

EDIT1: I just found a 'EQ overflowing' message in Xorg.log

[118142.110] [mi] EQ overflowing. The server is probably stuck in an infinite loop.

As a temporary workaround, you can try to insert something like:
chvt 0 ; sleep 1 ; chvt 7 to your (if any) hibernate/suspend script.
