+Subject: Bug 1819035 - get EGL display based on the used platform in the
+ browser r=webrtc-reviewers,ng
+
+Because of a possible misconfiguration or a possible driver issue it
+might happen that the browser will use a different driver on X11 and
+end up using yet another one for wayland/gbm, which might lead to not
+working screen sharing in the better case, but also to a crash in the
+other driver (Nvidia). This adds a check for platform the browser runs
+on, if it's XWayland or Wayland and based on that query EGL display for
+that specific platform, rather than going for the Wayland one only.
+
+Differential Revision: https://phabricator.services.mozilla.com/D171858
+Mercurial Revision: https://hg.mozilla.org/mozilla-central/rev/c8606497de1f461a6352456e0e511c2ae498d526
