listactivity is stuttering caused by WindowManager

i have a question regarding some weird logcat outputs.

Scenario: I have a li开发者_如何学Cstactivity with images and textviews, etc. The images are loaded by Fedor's implementation of LazyList. I changed his cache to a LRUMap from commons.

On scrolling i got sometimes a stuttering and logcats shows me a lot of this messages:

V/WindowManager( 2482): Dsptch > Window{48267640 <packagename to Listactivity> paused=false}
V/InputDevice( 2482): ID[0]=0(0) Up(1=>0)

Any ideas what these messages mean?

Thx in advance
