GTK theming is currently unstable and their css handling is changing between series so using the system theme wouldn't work great in practice, a snap of a GTK > 3.19 software wouldn't look right on an host using GTK 3.18
Options: - use the host theme via an interface, but then you get the issue if the GTK versions mismatch - have applications to bundle and force one theme, but the result is that they would not look integrated to the desktop environment they are used on - have applications to bundle themes for the different desktops and somewhat smart select the one to use ... that's probably not something an upstream wants to have to do since it would require to keep up with the envs existing out there and what theme they use - invent a smart theme interface where you get a snap with a collection of themes and the one shared with your snap is selected somehow depending on the toolkit (+version) and desktop theme you are using - other? I think ideally we need the smartness, unsure how it could work exactly though -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1585332 Title: Graphical snaps don't follow the window theme To manage notifications about this bug go to: https://bugs.launchpad.net/snappy/+bug/1585332/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
