            Bug ID: 103757
           Summary: eglGetDisplay() is broken for Wayland
           Product: Mesa
           Version: git
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: EGL/Wayland
          Assignee: wayland-bugs at lists.freedesktop.org
          Reporter: m.olbrich at pengutronix.de
        QA Contact: mesa-dev at lists.freedesktop.org

_eglNativePlatformDetectNativeDisplay() (called by eglGetDisplay()) detects
Wayland by checking if the native display object starts with a pointer to
wl_display_interface.

Unfortunately wl_display_interface is defined in both libwayland-server.so and
libwayland-client.so. libEGL links to both and in all my tests it always picks
the one from libwayland-server.so.
The wl_display object passed as native display however contains the version
from libwayland-client.so so the check fails.

There is an old thread about this[1] on the wayland-devel list, but it seems
nothing happened since then.
