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) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gtk+3.0/+bug/1572331/+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
