** Description changed: Hi, Marmuta wrote a patch for this issue, that I applied to the gtk+3.0 package shipping currently in the development version of Ubuntu zesty. You will find the corresponding debdiff attached to this bug thread. + + Marmuta performed tests with org.gnome.desktop.interface scaling-factor + = 2 , where few issues are left for Onboard on hidpi screens, that are + not related to gtk, but rather to unity-greeter or gnome-screensaver. He + did not notice any issue with scaling-factor = 1. Can a sponsor please review the debdiff? Thanks in advance. Francesco ============================================================================= - Original description: + Original description: See attached screen shot. Blue is a GtkPlug, black is a GtkSocket. Source code below. What I expect to happen is that the GtkPlug has the same size as the GtkSocket. What actually happens is that GtkPlug only covers a quarter of the area of the GtkSocket. Impact: Onboard on HiDPI displays is near unusable at login and lock screen, aka unity-greeter and gnome-screensaver. Original bug report here: https://bugs.launchpad.net/bugs/1562734. Steps to reproduce: - build plug and socket samples from below - set display scaling factor to 2 System Settings -> Display -> Scale for menu and title bars = 2 - run ./socket $(head -1 <(./plug)) -> blue GtkPlug is too small, it should cover all the black - resize the window -> at smaller sizes the scaling suddenly corrects itself, at larger ones it's wrong again ProblemType: Bug DistroRelease: Ubuntu 16.04 Package: libgtk-3-0 3.18.9-1ubuntu3 ProcVersionSignature: Ubuntu 4.4.0-18.34-generic 4.4.6 Uname: Linux 4.4.0-18-generic x86_64 ApportVersion: 2.20.1-0ubuntu2 Architecture: amd64 CurrentDesktop: Unity Date: Wed Apr 20 01:48:50 2016 SourcePackage: gtk+3.0 UpgradeStatus: No upgrade log present (probably fresh install) ** Summary changed: - GtkPlug scaled to half the expected size on HiDPI screens + GtkPlug scaled to half the expected size on HiDPI screens + zesty debdiff -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1572331 Title: GtkPlug scaled to half the expected size on HiDPI screens + zesty debdiff To manage notifications about this bug go to: https://bugs.launchpad.net/gtk/+bug/1572331/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
