Description Alain Knaff 2002-07-01 20:44:26 UTC
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:  
Steps to Reproduce:  
1. Start konsole, and admire that strange font! 
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...)

Comment 1 Bernhard Rosenkraenzer 2002-07-02 08:41:42 UTC
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).
