Subject: [PATCH xserver 06/27] xwayland/eglstream: Check buffer creation
|
||
|

EGLStream wl_eglstream_display_create_stream() may fail, yet Xwayland
|
||
|
|
would try to attach the buffer which may cause a fatal Wayland protocol
|
||
|
|
error raised by the compositor.
|
||
|
|
|
||
|
|
Check if the buffer creation worked, and fail gracefully otherwise (like
|
||
|
|
wayland-eglsurface does).
