Win8 Lenovo X1 Carbon with USB 3 Dock: Display Artifacts

[jeffhoward001]

I'm not sure if that's even a word ("pixelation"), but that's the best way I can describe it. Whenever an animation takes place in Win8 on my X1 Carbon w/ the Lenovo USB 3.0 dock, strange pixelation occurs on the screen (anywhere on the screen, not just the animation).

It's most analogous to a REALLY low-res jpeg, and is most obviously with high-contrast colors. What's weird is that it doesn't happen all the time. If I had to guess, I'd say about 50% of the time? I can't figure out what fixes it either as power-down reboots or undocking/redocking doesn't always fix it.

I dock/undock a couple times a day, and it's a flip of the coin whether the issue will occur. The easiest way to reproduce it is to roll the mouse over the icons on the taskbar. As it highlights the icon under the mouse, the other icons look like low-res jpegs.

To be clear, if it's not happening, then everything's fine. I can watch 1080p video with crisp graphics. When it does occur though, everything runs like crap. Even 480p video or moving around an MS Word document will cause the pixelation and high CPU usage.

Just want to be sure this is the same issue others are mentioning, and add a little more detail to the symptoms.

Thanks,
