Hi, I'm running F13 KDE nightly build (20100328) in VirtualBox and experience high cpu usage. top shows that X is the 'culprit'. Jaroslav Franek opened a report [1] for this issue. The issue looks very the same as stated in report [2]. Does anyone else have seen X using lots of cpu sources in F13? Thanks, Martin Kho [1] https://bugzilla.redhat.com/show_bug.cgi?id=577482 [2] https://bugzilla.redhat.com/show_bug.cgi?id=475890
