Description of Problem: qt-3.0.4-6 and qt-3.0.4-7 as shipped with rawhide break KDE. This can be seen by two symptoms: - konsole has a "funny" font (extra wide, doublespaced) - Passing the mouse cursor over the small icons in the quicklauncher panel applet "wipes out" those icons, especially those in the bottom row. qt-3.0.4-5 (which I fortunately kept around) works ok. Version-Release number of selected component (if applicable): qt-3.0.4-6 or qt-3.0.4-7 How Reproducible: Always. Steps to Reproduce: A: 1. Start konsole, and admire that strange font! B: 1. Pass mouse cursor over quicklauncher panel applet 2. Click on panel icons 3. Wait a while 4. You'll notice that a couple of icons in the lower row of the quicklauncher just disappear! Actual Results: Strange font in konsole (doublespaced: between each character, there seems to be an extra space character) Icons in quicklauncher disappear Expected Results: Normal font in konsole (as it was until 3.0.4-5) Quicklauncher icons should stay put. Additional Information: This problem has now been existing for over a week, (qt-3.0.4-6, the first to break this stuff is dated June 21st), with no sign of progress (qt-3.0.4-7 has been released with the same bug...)
The font problem is caused by fontconfig (new X font management system) trying to merge all possible charsets into one font, so konsole sees the width of Chinese/Japanese characters when determining the right spacing. The (not 100% reproducable) icon problem is also caused by the switch to Xft2, though I haven't debugged it enough to see whether it's a problem with Xft2 itself or with the way Qt uses it (the only change between 3.0.4-5 and 3.0.4-6 was adding support for Xft2).
