Still, Qt should not display garbage with it... This is also reproducible with Intel graphics according to: https://www.redhat.com/archives/fedora-list/2009-April/msg01110.html Reply at: https://bugs.launchpad.net/ubuntu/+source/qt4-x11/+bug/334657/comments/31 ------------------------------------------------------------------------ On 2009-04-14T17:56:52+00:00 José wrote: I was using an r300 with KMS as it can be seen here: http://lists.fedoraproject.org/pipermail/fedora-kde/2009-February/001479.html The fix was to remove the hinting: http://lists.fedoraproject.org/pipermail/fedora-kde/2009-February/001624.html Reply at: https://bugs.launchpad.net/ubuntu/+source/qt4-x11/+bug/334657/comments/33 ------------------------------------------------------------------------ On 2009-04-14T18:28:24+00:00 Rex wrote: Interesting, enabled full font hinting here in systemsettings, but I (still) can't reproduce.
