I got a problem in menu fonts. Some letters have gone crazy and I do not have any idea why so.

I do not say that this is Maemo's fault because I have installed couple of apps from extras-testing and extras-development, but anyway, if there is anything what I can do (except reboot the device), I would like to know how I can fix this. So this is not meant to blame anyone

For example there should be text "Puhelin" under Web but letter have a strange background like some other icons too. You can see it very easily even those are in finnish. Anyway, same problem occurs when I press "More".

Anyone else have this kind of problem?

Well, looks like a broken font.

Any ideas what can caused that? Yeah, I know that I have installed apps from testing and devel, but any ideas what could cause that? I just don't want to reboot if it is possible, so any ideas how to restart Xorg? There is no /etc/init.d/Xorg nor xorg. :/

Found a solutions without a reboot.

So in short. Login as a root (I used SSH). Then do:
/etc/init.d/hildon-desktop stop

That will kill the window-manager/desktop/whatever. After that do:

/etc/init.d/hildon-desktop start

After that it will start again. In my case that helped! Linux rocks =)
