In KUbuntu Jaunty widgets are drawn wrongly in some styles.
Or, to say more precisely: initially (when window just shown) they are drawn right, but then (when I focus them, or mover mouse over them, or type into them, etc) they are refreshing/redrawn in wrong way.
The most noticeable is Cleanlooks widget style. I've attached screenshow of krusader search dialog in the Cleanlooks widget style (I've just opened it, pressed Tab key several times, and made screenshot).
Some other styles also work not well. Particularly:
1. In Plastique style when I type text in editbox I get black rectangle over the last letter.
2. In QtCurve style some minor issues present directly in the SystemSettings app.
Also, somewhy, Psi (both packaged and manyally compiled versions) draw widgets wrong in any theme.
I've forgot...
1) The release of Ubuntu you are using, via 'lsb_release -rd' or System -> About Ubuntu.
Description: Ubuntu jaunty (development branch)
Release: 9.04
Actually, I'm using KUbuntu Jaunty Alpha5.
2) The version of the package you are using, via 'apt-cache policy packagename' or by checking in Synaptic.
I cannot run 'apt-cache policy' since I don't know package name.
3) What you expected to happen
Obvious - I extecped widgets to redraw correctly.
4) What happened instead
Already described.
I don't use any proprietary drivers.
