Running now for about 45 minutes, and the stutter appears to be gone! I'll report back if I see any glitches.

Regarding wireless mouse interference, I experience issues when my Logitech Unifying USB receiver is plugged directly into one of the USB 2.0 ports (on the back of the Plugable UD-3000). No idea why, as I thought that the interference was limited to the 3.0 ports. I have the receiver on a 3 foot USB extension cable, physically placed about a foot from the Plugable, and it works fine... Go figure.

I've been troubleshooting the lag and blinking issues for a week now, just finding this thread today. Good timing - I tried Wim's pre-release drivers and things are better. The blinking when docking Xbox Music on the side in Windows 8 no longer happens, and the general mouse lag does feel better. I wouldn't say it's as smooth as working directly on the laptop (Dell XPS 12), but it's within the realm of acceptable now.

I look forward to further improvements!

Update a few hours later: looks like I spoke too soon. Although the lag is maybe a little better, it's still noticeable. The blinking to black is there, too, but it's different now. It seems to blink more quickly and less often than before. Also, I'm running two DVI monitors and one of them only has the Zune client in "tiny" mode to play some music. When I hit the Windows key to bring up the new start menu, there's a definite pause for a second.

Wish I could report an improvement but I'm still in the same boat. If anything I would say it maybe even got a little worse with that update.

I really appreciate the effort though! Nice to see a company posting potential fixes like this within a thread rather than making their users wait.

I see from an earlier post you are using the Lenovo X1. Can you check all the drivers are up to date on this platform, including the BIOS and see if this makes a difference. I think I saw a user earlier in this thread who found this helped.

Also, make sure you are using the "High Performance" power profile, rather than "Balanced" when plugged in. This could also slow down our software's performance.

After some playing around, including the pre-release driver Wim posted and doing the crazy USB 3.0 driver hack, the mouse lag problem is almost gone for me. I think it's close enough that I'll be able to look past it while we wait for a rock solid driver. If no docking were like running a game at a constant 60 frames per second, it now feels like 60 FPS with an occasional dip to 50 FPS. Not terribly significant, but it's there.

You know what the biggest difference has been? As mentioned by Wim, changing the power mode to High Performance. It's strange, though, because my Balanced profile has everything set on the highest performance settings when plugged in. The High Performance profile must do other stuff under the hood that can't be controlled with the UI. When I switch to Balanced, the mouse will skip around when moving over Outlook. In High Performance, it's pretty much as smooth as when not docked. Weird, but I can handle having to switch when docked. Obviously it's not ideal, but it works.

Give it a shot and post your results.

Dell XPS 12
Targus USB 3.0 dual video dock with power
Two Samsung 24" monitors going over DVI (one of which converts from HDMI coming out of the dock)
Back to original Microsoft USB 3.0 eXtensible driver
Latest Intel HD Graphics 4000 driver from Intel
Wim's pre-release DisplayLink driver for the dock
Windows 8 64-bit

So the development BUILD posted by Wim is newer than the 7.2M1 posted on the displaylink website? I too have the mouse getting stuck randomly for a few seconds.

Edit: UPDATE
Ok so the BUILD is newer and supposedly fixes the mouse freezing issue but brings back the horrible screen rendering. Minimizing a window or switching between classic and modern UI (Windows 8) is just quite bad. The mouse pointer speed also suffers. *Sigh*

Not posting to refute the experience of others -- but my install of the development driver is still going strong on my Lenovo Twist with Windows 8 (64-bit). For the record, my earliest install of the Windows drivers was M0, I've manually run the DL install (vs. using Windows update) for the M1 update, and I never attempted the USB driver tweak, despite M0's problems.

Granted, my install is still fairly stock, but the differing experience of others here is a little disconcerting. It'll certainly give me pause with future software updates, as things appear to be somewhat frail...

It should not have regressed the fuzziness that was seen before. What is your system spec? Have you tried "High Performance" mode if you have a tablet with this setting, as it could help.
