I did install Mint 17 (Qiana) today and I seem to have problems with the window title bars such as chromium title bar. I have limited knowledge of tool kits such as qt or gtk.From what I read so far, they seem to be two libraries/framework satisfying the same purpose. so on a system with one desktop environment such as gnome, I believe there should be only one framework installed gtk in this case?Or is there a problem with the window manager?I was trying to install virtualbox but I found only virtualbox-qt, but later I uninstalled the package and purged conf files.Is it normal that I see a lot of other qt libraries installed on the system?gtk libraries:ii  gir1.2-gtk-3.0

chrome ui issues with mint 17
linux mint;gtk;qt
It seems absolutely normal to have those packages installed. On my system Mint 17 system I have the same. If you think there are libraries left that are no longer needed you can always issue a:sudo apt-get autoremoveto get rid of them, but I guess that will not bring you anything.If you have apt-rdepends installed you can can use:apt-rdepends -r --state-follow=Installed --state-show=Installed libqtdbus4to see what (reverse) dependencies for an installed package on your system. (You can also use apt-get remove packagename and then abort the action as a primitive alternative for seeking out dependencies).From the above apt-rdepends invocation it looks like vlc is the program that is installed by default and requires the qt libraries.
