Status in Clutter GTK: Fix Released Status in clutter-gtk package in Ubuntu: Fix Released Status in clutter-gtk source package in Trusty: Fix Committed Bug description: SRU Justification: [Impact] The video playback under HiDPI display with scale factor 2 doesn't work well on Ubuntu 14.04. [Test Case] It is easy to reproduce the problem on non-HiDPI display by the following command. `GDK_SCALE=2 totem /usr/share/example-content/Ubuntu_Free_Culture_Showcase/How\ fast.ogg` There is no problem in Ubuntu 14.10 because the upstream's fixes are included. [Regression Potential] Backporting clutter-gtk upstream patches already in 14.10: GtkClutterEmbed: Scale allocation by the scale factor embed: Pass scaled size back to clutter To manage notifications about this bug go to: https://bugs.launchpad.net/clutter-gtk/+bug/1401376/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
