Many qt4 applications use 100% of cpu, when qt4 is compiled with glib event loop. For example, qjackctl and qsynth. Works fine with USE=-glib flag. qt version is 4.3.3
Not here... So, if you can tell us which ebuild versions is this about, how to reproduce the problem, post required information such as emerge --info output etc., then reopen this bug. Thanks. http://www.gentoo.org/doc/en/bugzilla-howto.xml
