Hi, [This message is resent without the attached figure which turned to be huge, I will place another version available, but the rationale is that fonts are completly garbled for kde4 applications] I have updated qt to 4.5 in F-10. Apparently I have the same problems I had before in rawhide. After the update kdm is not an option anymore as the kmgreeter crashes. The crash report is attached. I had to change to gdm. Then I have the problem with fonts for all kde applications (but not for plasma as it can be seen in the attached figure) each character becomes fuzzy. Notice that this does not happen for graphical applications, xterm, firefox or any gnome application work right. Just to the test the other option I have changed to gnome and there that problem does not show any more. I am typing this message in kontact (kmail) and the fonts are crispier than ever. :-) So it seems as if there is some kind of interference between kde and qt (but not plasma). Suggestion (other than a downgrade) are welcome. :-) -- Jos?
