If you’re familiar with the Raspberry Pi desktop experience, you’ll have noticed that windows on the desktop can be a bit slower to move around than you’re used to on your PC or laptop. This is because X, the windowing software (or composition protocol) that we use, is not optimised to use the graphics core of the BCM2835, the chip at the heart of the Raspberry Pi. All the work is done by the ARM processor instead, which slows things down and leaves the graphics core twiddling its thumbs. That graphics core is extremely powerful, so we’re working on putting it to good use to fix the issue.
