Subject: [PATCH xserver 16/27] xwayland/eglstream: Do not commit without

surface

The EGL surface for the xwl_pixmap is created once the stream is ready
|
|
|
d05f4b |
and valid.
|
|
|
d05f4b |
|
|
|
d05f4b |
If the pixmap's EGL surface fails, for whatever reason, the xwl_pixmap
|
|
|
d05f4b |
will be unusable and will end up as an invalid wl_buffer.
|
|
|
d05f4b |
|
|
|
d05f4b |
Make sure we do not allow commits in that case and recreate the
|
|
|
d05f4b |
xwl_pixmap/stream.
