From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.2b) Gecko/20020922 Description of problem: I installed qt2-2.3.1-8 and Opera 6.03. I exported QT_XFT=True and then launched Opera. Fonts were not anti-aliased. Since it had worked on RedHat 7.3, I down-graded qt2 with qt2-2.3.1-3, which was shipped in 7.3. Now fonts are anti-aliased. But the application frequently crashes. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1. Install qt2 2. Install Opera 6.03 3. export QT_XFT=True 4. Launch Opera Actual Results: Fonts are not anti-aliased. Expected Results: Fonts should be anti-aliased. Additional info: Replaceing qt2 in 8.0 with the package in 7.3 will make fonts anti-aliased. But this will cause a lot of crashes.
it's fixed in fc current release.
