Description Malte S. Stretz 2005-03-04 01:18:56 UTC 
Version:           0.4 (using KDE 3.4.0, Gentoo)
Compiler:          gcc version 3.3.5 (Gentoo Linux 3.3.5-r1, ssp-3.3.2-3, pie-8.7.7.1)
OS:                Linux (i686) release 2.6.10-gentoo-r4

On my 1280x1024 screen with a maximized KControl, the preview in the Theme Manager looks ugly as hell because it is scaled up to a size where everything is just blurred.

The preview should not be scaled, or only scaled down if the window is too small, but never up.

I agree. But as it seems to be added intentionally (kthememanager.cpp#392) let's hear what Lukas says against removing the scaling.
