I just upgraded from koji after the mass rebuild. Note that I had an up-to-date rawhide from this morning just before the upgrade. There are a couple of obvious problems, at least for me. Buttons in firefox/minefield are huge to the point where all web pages are unreadable. I backed out the xulrunner and gtk2, also tried changing gnome default themes/icons with no success. All gnome terminal text (both typed and prompt) has a red background. The settings in the terminal profiles don't help to fix it. I looked in the bash man page but so far haven't found a setting that might fix it there. darrell
