Confirmed this is occurring in git master - suspecting that something changed inside GTK+.

Not sure if that's the GTK backend or Mir to blame Small example attached, the program has a button and a label, click on the button should display "clicked!". Under unity8 the button seems to stop reacting after the first click and sometime the program closes (compile with "gcc button.c -o button`pkgconfig --cflags --libs gtk+-3.0`", to run it you need to have a .desktop running the binary and including the X-Ubuntu-Touch=true key) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gtk+3.0/+bug/1388875/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
