DL-195 bitmap sluggishness
 

So I replaced my Kensington adapter with a Diamond BVU195, which is a DL-195-based adapter. The latest and greatest, according to the DisplayLink website.

Well, on one hand, it fixed the awful coloring problem I describe in a different thread, but now this adapter is ridiculously sluggish when drawing any bitmaps or large widget redraws (e.g. even the Start Menu redraws slowly).

See the problem in action here:

I fully understand that writing USB drivers is no walk in the park, but in my experience with two different adapters, the 1.5b driver branch needs a lot of help.

Hmm you cables are good and plugged into the system directly or over a hub ?

Hub. Does it really matter?

Well depends on the HUB - "we've seen things you people wouldn't believe ..." ;-)

Anyways try it directly and with two different cables just to be sure it has nothing to do with the hub or the cables.

Hello.
You made some good points there.
