Some apps fail to start under openSUSE Tumbleweed:

Confirmed locally after switching to wayland. The fix included one permission:

owner /run/user/*/mutter/Xauthority r,

I'll coordinate with Jamie for fixing this.

https://github.com/snapcore/snapd/blob/master/interfaces/builtin/x11.go#L131 already has:

owner /run/user/[0-9]*/.mutter-Xwaylandauth.* r,

Looks like Zygmunt's addition should be added under that.

[Zygmunt Krynicki (zyga)]

The fix is proposed in: https://github.com/snapcore/snapd/pull/7422

[Zygmunt Krynicki (zyga)]

The fix was released to tumbleweed now.

[Zygmunt Krynicki (zyga)]

Correction, this is cherry picked into 2.41-1, sorry for the confusion.

Confirming fixed on up-to-date Tumbleweed, thank you a lot!
