+            Thank you for the report, but your issue does not look like it would belong here. Sorry.
+
+            This repository is for the Wayland protocol specification and the
+            low-level C library that deals with the protocol.
+
+            This issue here is a bug not with the protocol itself but with either
+            - your compositor or desktop environment's implementation of the Wayland protocol and surrounding functionality,
+            - the individual application that triggers this issue, or
+            - the kernel driver used by your hardware
+
+            Please file the issue against your compositor/desktop environment, the application
+            or the kernel drivers instead, whichever seems more likely to you. If you are not sure,
+            file an issue against the application.
