Description Christopher Yeleighton 2011-06-16 12:18:24 UTC

Version:           1.6.6 (using KDE 4.6.0) 
OS:                Linux

Wheel scrolling in the preview window scrolls only a part of the document, the central part of the display remains unaffected.

Reproducible: Always

Steps to Reproduce:
  1. Select a long HTML message in a feed.
  2. Hover over the Preview window.
  3. Rotate the mouse wheel upwards.
  4. Rotate the mouse wheel downwards.

Actual Results:  
  1. Akgregator shows a fragment of the message in the Preview window.
  3, A small fragment at the top scrolls upwards, the display is inconsistent.
  4. A small fragment at the top scrolls downwards, the display is inconsistent.

Expected Results:  
  3. Let the whole document scroll upwards.
  4. Let the whole document scroll downwards.


OS: Linux (x86_64) release 2.6.37.6-0.5-desktop
Compiler: gcc

The display returns to a consistent state when you force a redraw of the preview window by placing some other window over it.

You get the same effect by pressing the single-step buttons in the vertical scroll bar and up/down keys.

And by dragging the scroll bar,

Stand-alone browser tabs are unaffected.
