I accidentally installed GNOME with these commands:sudo apt-add-repository ppa:gnome3-team/gnome3-stagingsudo apt-add-repository ppa:gnome3-team/gnome3sudo apt-get updatesudo apt-get dist-upgradeAfter I rebooted my computer, some of the GUI parts like the outlines of buttons were gone:I have tried to remove the PPA's and update, but that didn't work.
My windows doesn't render properly
