Description Bastien Nocera 2014-09-15 14:05:34 UTC 
Created attachment 286206 [details]
gtk-clutter-multistage.c

Test program attached. You'll also need the patches from bug 736564.
Comment 1 Bastien Nocera 2014-09-15 14:07:39 UTC 
From the other bug:
I get:
- 2 flickery video displays when using cheese (which doesn't use a GtkStack)
- mouse events going nowhere (buttons not working, hidden video texture) in totem

I can reproduce the latter with another test program. Given that it only
happens when using clutter-gst inside clutter-gtk, I would consider it a
clutter-gst bug.
Comment 2 Lionel Landwerlin 2014-09-15 22:43:21 UTC 
Is this what you're expecting : https://www.youtube.com/watch?v=lLbFqO9XDRo ?

You have to initialize clutter-gst before clutter-gtk, otherwise cairo crashes. I think this problem has been reported several times already.

Also no need for file:// in clutter_media_set_file().
Comment 3 Lionel Landwerlin 2014-09-16 19:28:18 UTC 
Right, I completely missed the wayland part of the bug.

I just used jhbuild to get weston + clutter + clutter-gtk + clutter-gst and ended with an application that draws itself exactly once and then blocks forever in a glClear :

Program received signal SIGINT, Interrupt.
0x00007ffff1e6e0ed in poll () at ../sysdeps/unix/syscall-template.S:81

Let me know what's your setup and your mesa version.
Comment 4 Bastien Nocera 2014-09-16 19:42:15 UTC 
jhbuild versions of gtk+, clutter-gtk and clutter-gst.
clutter from the distro: clutter-1.19.8-1.fc21.x86_64
I ran this under gnome-shell's wayland session in F21.
Comment 5 Lionel Landwerlin 2014-09-16 20:51:12 UTC 
Anyway to test this stuff under X?
Mutter used to have a nested mode according to https://wiki.gnome.org/Initiatives/Wayland/TryingIt
What happened to that?
Comment 6 Lionel Landwerlin 2014-09-16 21:13:36 UTC 
Ok, same problem with nested wayland.
What's your version of Mesa?

I don't know. I wish it was easier to test as well, but I make do with the gnome-shell wayland session.

mesa-libEGL-10.3-0.rc1.20140824.fc21.x86_64
Comment 8 Lionel Landwerlin 2014-09-16 21:27:30 UTC 
Actually you can compile mutter in jhbuild with xwayland and it works nested like this :

mutter --wayland
Comment 9 Bastien Nocera 2014-09-17 17:49:15 UTC 
Sorted inside clutter-gtk itself now. Apologies for the red herring :/
