Compositing |
Quartz Compositor is the display server (and at the same time the compositing window manager) in macOS. It is responsible for presenting and maintaining rasterized, rendered graphics from the rest of the Core Graphics framework and other renderers in the Quartz technologies family.[1]
Overview[edit]
The bitmap output from Quartz 2D, OpenGL, Core Image, QuickTime, or other process is written to a specific memory location, or backing store. The Compositor then reads the data from the backing stores and assembles each into one image for the display, writing that image to the frame buffer memory of the graphics card. Quartz Compositor only accepts raster data, and is the only process that can directly access the graphics frame buffer.[2]
In managing individual windows, Quartz Compositor accepts a bitmap image of the window's contents from its renderer, along with its position. The choice of the renderer is up to the individual application, although most use Quartz 2D. Quartz Compositor then acts as a 'visual mixing board,' by adding the given window to the whole scene for the display.
In its role as window manager, Quartz Compositor also has an event queue which receives events, such as key strokes and mouse clicks. The Quartz Compositor takes the events from the queue, determines which process owns the window where the event occurred, and passes the event on to the process.[3]
Quartz Extreme[edit]
Mac OS X v10.2 introduced Quartz Extreme: graphics processor (GPU) acceleration for the Quartz Compositor. With Quartz Extreme, far fewer central processor (CPU) cycles are needed for scene composition. Instead, the Quartz Compositor encapsulates each rendered backing store in an OpenGL texture map or surface. It then directs the GPU to compose the surfaces and maps to provide the final image, which is delivered to the frame buffer.
Quartz Extreme only uses OpenGL commands, and requires a graphics card connected to an AGP 2X or faster bus (including AGP 4X, 8X, and PCI Express), supporting textures and maps of arbitrary size, since many of the renderers have no size limitation (Quartz 2D for example).[2] In Mac OS X Tiger, it is automatically enabled on Mac systems with one of the following types of graphics cards:[4]
- AMD (ATI) Radeon, AGP-based, 16MB VRAM minimum, or better
- NVIDIA GeForce2 MX, 16MB VRAM minimum, or better

As of OS X El Capitan, Quartz Extreme is enabled on all supported Macs.
QuartzGL[edit]
QuartzGL (called Quartz 2D Extreme when it was introduced in Mac OS X Tiger) is GPU acceleration for the Quartz 2D API. With QuartzGL enabled, all Quartz drawing commands are translated to OpenGL commands and executed on the GPU. This differs from Quartz Extreme, which still executes Quartz drawing commands on the CPU but performs final composition using the GPU.
As of OS X Mountain Lion, QuartzGL is still not enabled by default. However, it is possible to enable it using the Quartz Debug application included in the Apple Developer Tools. QuartzGL will be disabled once again upon quitting the Quartz Debug utility. A workaround is to force quit the Quartz Debug application, which will leave QuartzGL enabled system-wide.
All graphics cards capable of supporting Core Image also support QuartzGL.

For several months I have struggled to resolve an issue with my early 2009 24-inch iMac 3.06 GHz Intel core 2 Duo. I have visited two Mac repair places, one of which took the machine to the Mac bar and had the power supply and graphics card replaced, but nothing has solved the problem. Neither repair place could fault the machine in testing.
Symptoms include a flickering screen and screen tearing (small portions of one part of the screen appear on other parts of the screen), strange pixelation often in green and purple, followed shortly by the computer freezing. Sometimes if I leave it for five or ten minutes the mouse comes back to life but nothing else and then I'll often get kernel panic. Heavier graphics use (photo editing or image-heavy browsing) seems to make the problem present sooner - within half an hour.
Sometimes, if I have music playing when it freezes, I can hit the volume button and about ten minutes later the volume will change accordingly. This hints at (severely delayed) hard drive activity in the background.
The latest repair place (Mac & PC Doctor) drafted the following report:
'• Ran Memory Test over night - on all Installed RAM to confirm that the Linear PRN and stuck address is returning correct information- All ram memory test passed..... No fault found.
AST (Apple Service Test) Ran: Tested Logic Board• SD Board• Bluetooth • AirPort Display • Camera •Apple USB Input Device • Optical Drives • Ethernet •Hard Drive • Power Supply (desktop Macs only) • Fans, GPU (Video Controller)• Sensors •Processors & Memory : Pass - All components Present
Tested via customers OS - No fault found
Having troubles faulting the unit.
All HW passes all of our tests which indicates a intermittent SW fault.'
They suggested the problem could be an intermittent power supply in my flat. I have moved the computer to a different room but the problem persists. I have considered buying a UPS but I have serious doubts that power supply is the problem given it has only presented in the last four or five months and I've been in the flat for much longer.
I have reinstalled OSX Lion. I have been running a piece of developer software called Quartz Debug, with which I have been disabling Quartz Extreme and 2D acceleration, which while diminishing graphic performance seems to allow the computer to run for longer without freezing and/or crashing. But in the end it always freezes.
The machine is out of warranty. It is basically unusable in its current state. I really am at a loss and can't think what else to do other than to throw it in the bin and buy something else. Any assistance would be greatly appreciated.
