Description kde 2011-10-27 16:43:10 UTC

Version:           unspecified (using KDE 4.7.2) 
OS:                Linux

I am running kde on a 2007 thinkpad T60 with ATi graphics using open drivers.

With desktop effects on there is a blocky breakup of the window when it is being scrolled through.  This is cured when the scrolling stops, so is a problem with smoothness of movement only.

I don't remember this in 4.6.

Reproducible: Always

Steps to Reproduce:
turn on desktop effects, scroll

Actual Results:  
as above

Expected Results:  
smoothness!

Does this only happen when there are windows below the window where you scroll, or also when it is the only window on screen?

Comment 2 kde 2011-10-27 19:52:46 UTC

After a bit of experimenting it doesn't seem to break up when it is the 
only window open.

hope this help

sorry, but I don't get what you mean with "break up". A screenshot or screencast might help to understand.
