Description: If you click on a dragable bar of a GTK3 application (i.e. primary toolbar / menubar), move the window and click at a non-dragable area, the window moves around widely without any logical direction. How to reproduce: Click on a dragable bar, move the window, click somewhere else in the window. Expected behaviour: The window does not jump or move around. Actual behaviour: -> attached video at bugzilla.gnome.org Further information: I've reported this issue also to the GTK+ bugzilla: https://bugzilla.gnome.org/show_bug.cgi?id=675613 This is a regression in GTK+ 3.4, I'm not able to reproduce it with 3.2. Strange is however, it is dependent on the window manager. This bug does occur with XFCE and GTK+ 3.4.3 but not with Gnome 3.4.
also bugreport on launchpad related to ubuntu https://bugs.launchpad.net/ubuntu/+source/gtk+3.0/+bug/1001936 I'm expiiencing same problem especialy with shotwell's editing dialogs. This bug can not be reproduced with fluxbox, so I think it's xfwm's bug.
Happening for me as well. XFCE 4.10, GTK 3.4.3. Issue only occurs with GTK3 apps like Evolution. Can reproduce based on Thomas's description.
Comment https://bugzilla.gnome.org/show_bug.cgi?id=675613#c5 is key and much helpful.
Fixed in git with commit 099614e
Thanks a lot, the patch works fine. :)
