gnome renders bigger app menus's font size than kde, on some apps like skype and k3b. despite of the general font size on gnome is setted to 10, on those apps looks like 14.
I saw font-related posts in here, but noone match exactly this my case.

anyone has experiensed this, and / or know how to fix it?

regards

You may want to try one of these applications:

gtk-chtheme
http://plasmasturm.org/programs/gtk-chtheme/

gtk-theme-switch
http://www.muhri.net/nav.php3?node=gts
(Note that there are 1.x and 2.x versions for changing the gtk1 and gtk2 themes).

You should be able to also change the fonts with them.
Cheers.

Have a look at System>Preferences>Fonts

I guess the problem is not in gtk, but in the way some programs not made using gtk, renders under gnome.

I found a 'poor method' to not to fix, but to decrease this charasteristic: to set the kde overall fonts couple of points lower, so when such apps are opened on gnome, it fonts shows (just) 2 points more than the rest.

I'm still wonder about 2 things:
1) in which programm language were made apps like slackins, skype and k3b? maybe in sort of 'kde-specific' language? -seems like the problem resides between such language and the "(?)gnome render engine" (or however it is called)

2) why such behaviour doesn't occur under others VMs like fluxbox, where fonts are rendered exactly like in kde? -maybe coz they do not use that 'gnome render engine' ?

thanx again.
