The problem occurs also on vesa and nv drivers.
Everything is OK on a new created account.
I disable subpixel via systemsettings.

EDIT: Problem solved by removing ~/.fonts.conf

This helped me to get desired font rendering back after upgrading to Qt-4.5:

Re: problem after upgrade to Qt-4.5.0

@Salamander1978 First thank you very much for the link. I take the information from there and his included links to change my configuration in /etc/fonts which gives me a better look in kde3 and gtk apps.

So, again to this and the other hints: It doesn't matter if i remove my ~/.fonts.conf and all the conf files from /etc/fonts/conf.d which includes hint, antialias or rgb. The result is even the same and i step back to the elder qt. This is no problem because still again i use kdemod3 and i use my own packages for the important qt4 apps.

This problem occurs on Intel, too.

However, only vertical subpixel hinting causes problems. Fonts look just fine with horizontal hinting.

This happened to me immediately after installing truetype fonts, identical to your picture. Disabling the sub-pixel stuff (in the file mentioned in that thread) indeed fixed the problem for me. I commented all my trials and eventual fix in that thread. I did remove the ~/fonts.conf or whatnot as well and it worked for a little while until I installed some other things. Those who still haven't managed to fix it might have more luck looking over that way. The strange thing is I don't recall ever enabling this feature myself. I did try it on vesa and nv, and the same thing happened.

Re: problem after upgrade to Qt-4.5.0

Well, I'd like to have subpixel hinting on all the time, since fonts are awfully blurred without it. Horizontal hinting still works fine, but that's useless with my vertical LCD. (In fact it would just make things worse.) Vertical hinting is simply broken in Qt 4.5. Deleting .fonts.conf, .fonts and .fontconfig did not change anything. The file ~/.kde4/share/config/kdeglobals contains the correct value for subpixel hinting, exactly the one shown in systemsettings. (Simply put, rgb works, but vrgb is a showstopper.)

Re: problem after upgrade to Qt-4.5.0

@andrej Thanks for the info and i have the same problem because i use vrgb too. I'm only a little bit surprised that i have this settings in my kdeglobals (kdemod3) too because  i use "System Settings". Should i delete this lines in this case?

Re: problem after upgrade to Qt-4.5.0

I had a problem with fonts too, corrected by resetting fonts.conf, but is that really a Qt4.5 issue or is it just because your kde version was compiled against Qt4.4.3 ?

Re: problem after upgrade to Qt-4.5.0

@ChoK I have the same problem if i start in runlevel 3 and use openbox with startx (and no antialisaing and no subpixel rendering) to have a minimal enviroment. Running than qtconfig looks in the same way bad. I think that Andrej finds out the reason why some people can enjoy it without problems and some not. Great work.
