Version: (using Devel) Installed from: Compiled sources double sized-pixels: incorrect panel icons rendering Originated from: http://bugs.kde.org/show_bug.cgi?id=166646#c2 Go to sys.settings and use double pixel size for icons. It will change the icon size but not the element (like Kmenu) size nor panel itself -- so icons are cut in half (heigt) and in half they overlap (horizontally). This bug does not affect taskbar and systray.
The issue here is that Plasma::Icon does not deal with the enlarged icons properly. The Panel shouldn't magically double in size because of this setting - the icons on the panel adapt to the size the panel gives them. However, Plasma::Icon isn't taking into account that this setting makes the icon twice as wide and twice as high as it asked for.

I've noticed that Dolphin, for example, can't deal with this setting either. I'm not sure it should exist at all. The default icon sizes should just be made bigger if the user wants bigger icons.
double sized pixel icons are now gone; the a11y people say they were obsoleted by things like monochrom icons and the kwin zoom tools.
