Arch Linux

Description:

The last stable release/tag of cairo was 9 months ago. Since then, hidpi support that is critical for dependant packages (specifically gtk3) has been added.

Because there is no new version of cairo yet, gtk3 silently disables its own hidpi support if the required api is not found in cairo.

To work around this, non-rolling distros have been snapshotting cairo master (or previous, but including hidpi commits) and releasing that to their distro.

I understand Arch's policies, but I think in this cases some exception is warranted, and a roll-up patch should be applied for the Arch build of this package, to include hidpi support. As it currently stands, a new install of Arch, fully up-to-date, on a system with hidpi display, in either Gnome-Shell or Cinnamon, gtk3 programs appear broken, display at 1/4 of their proper size, and any icons are not scaled.


Steps to reproduce:
Run any gtk3 program (i.e. nautilus or gedit) on a hidpi system running on a hidpi-aware desktop environment.

Current workaround:
Build cairo from git (HEAD) and install
Re-Build gtk3 (current stable release)
