HD4600 Tearing Problems

[sl33nyc]

I'm just affirming @lumberjack88's reported issue with the Intel HD4600. I also have the same configuration:

MB: GA Z87M-D3H
CPU: Intel i7 4770K
GPU: 4770K's 4600 HD IGFX

and am experiencing the same visual tearing on Yosemite (10.10.1) with Multibeast 7.0.2. I did have the UEFI/BIOS set to use >64MB of graphics RAM, so I set it down to 64MB but still see the visual tearing. bdmesg also reports:

---------------------------------------------
------------ INTEL DEVICE INFO --------------
---------------------------------------------
Class code: [0300]
Intel HD Graphics 4600 [8086:0412] (rev 06)
Subsystem: [1458:d000] :: PciRoot(0x0)/Pci(0x2,0x0)
Using 0D220003 for ig-platform-id

so setting the IGPlatformID to 0D220003 seems unnecessary.

Scouring the forums for direction hasn't been fruitful.

I've tried your suggested settings (64MB IGFX RAM, new IGPID) Adrian, and it seemed to work at least in some situations. If I freshly start up the PC, there seem to be no tearing problems, at least I've not encountered them during the latest start ups, but if the PC goes into hibernation mode and I reengage the system through mouse movement or keystrokes, the tearing problems reappear. What is so special about the hibernation mode that it introduces these tearing problems once the PC is woken up?
