Hello,
I’m not sure if this is a Fedora specific thing, if something in the current packages is making this bug show up again, but I’m experiencing the exact symptoms described here: https://bugs.kde.org/show_bug.cgi?id=500366
Given that that bug has been reopened already, it would suggest it may be an underlying KDE issue.
However, downgrading the installed Fedora KDE packages to 6.4.5 makes that bug go away and paste works reliably 100% of the time from my testing. So I’m kinda unsure
This has already been reported in the KDE discuss forums as well, I figured I’d ask here just in case.
Thank you
