Comment 44 for bug 1590561

There are several separate issues here, and it doesn’t help that they are being tracked in the same place.

IIUC, the issue with the webbrowser-app snap on unity8 needs to be addressed in unity8 by relaxing the confinement that will allow apps to create a QOpenGLContext ("/dev/dri/*"?). It’s unclear to me whether the changes need to happen in unity8 itself, or in the "mir"/"unity8" interface definitions in snapd.

Regarding the other issue, the apparmor profile for webbrowser-app needs to be updated to use the ibus and nvidia abstractions. The profile is generated from a manifest, see https://bazaar.launchpad.net/~phablet-team/webbrowser-app/trunk/view/head:/debian/webbrowser-app-apparmor.manifest. IIUC, this won’t be sufficient to fix the issue, as the nvidia abstraction also needs to be updated. /etc/apparmor.d/abstractions/nvidia belongs to the apparmor package.
