I already use the latest DirectX and VideoCard drivers for my system.
I just ran a number of tests including disabling and enabling video in dxdiag; turning off my second monitor; Direct3D and Open GL performance.
Nothing changed this.
I did find that the problem for me was in my high resolution and how much of the LB I was showing. The more images shown, the greater the visual distortion. Also, the more images shown the slower I have to move the scroll bar in order to keep it smooth.
Normally I keep MC so it shows about 36 Albums.
If I shrink MC, so it only shows 20 @ 2 x 10 (20 Albums) things are very smooth no mater how fast I scroll. Additionally, in order to keep it smooth with 3 columns, I can only have 4 rows (12 Albums).
Sorry, but in light of what I just found I would like to request a customization option be implemented after the release of 11, so I can show less columns in the LB and eliminate the visual distortion of scrolling.
