[Jithin Emmanuel]

Applications like amarok, kmail, dolphin, dragon player has some parts of the display corrupted. which can be removed by making them redrawn on screen but reappears.
I am attaching screenshot of them.

Also I noticed that this problem might be with oxygen kwin style. I have been trying with plastique style for a day and so far there is no corruptions other than the dragon player full screen scroll bar.

When i was using kde 4.2 with qt 4.4 there was no such corruption problem.
