Mini DisplayPort adapters creating jumpy mouse cursors
Apple's Mini DisplayPort to Dual-Link DVI adapters finally started arriving – over two months after their introduction. These little doohickeys allow you to run a 30-inch monitor with the new MacBook Pros.

After waiting this long, however, users have reported that they cause the mouse cursor to jump while tracking. This has been confirmed with wired and wireless mice, and with two different adapters.

Not only did Apple charge users $100 to use their Cinema Displays and make them wait over two months, now they don't even work properly. People are pretty fired up about it and understandably so.

There has been no resolution to this as of yet, but plenty of people have stepped forward with the same problem. Together, they have made some interesting observations, such as multiple, repeating messages in the system.log. You can read all about it in this forum post.

There are other issues cropping up with this adapter too. This forum details an apparent DVI sync problem. Gizmodo recently published a report on periodic distortion issues when using the Mini DisplayPort to Dual-Link DVI adapter.

If you're experiencing problems with the adapter feel free to add to the threads (1, 2) on Apple's discussion boards. If you just want to mock Apple or otherwise post snarky comments about build quality, well, feel free to do that in the TalkBack here.
