[jbosstools-dev] Eclipse Luna M4/GTK3 still not usable in FC20

Hi guys I got a new machine over the x-mas holydays and installed FC20 onto it. Luna M4 still is not usable for me on this latest Fedora release, the package explorer and the editors are just empty (see attached screenshot). I have to switch back to GTK2 to be able to use it. Am I the only one that is experiencing this (looks like I'm the only one reporting this so far)? Cheers André
