+
+This template is for situations where you expect something to work but it doesn't. You do not have to use it for feature requests.
+
+Attach the full log file from the session during which the problem occurred: `jay log --path`.
+
+If the problem occurred during one session but not during another, attach the log file from the working session as well.
+
+If the problem relates to a particular client:
+
+- Start the client with `WAYLAND_DEBUG=1`, redirect stderr to a file, and attach that file.
+- If the problem is only present sometimes: attach two files: one created while the problem was present and one while it was absent.
+
+If the problem relates to display devices:
+
+- Attach a file containing the full `jay randr` output.
+- Attach a file containing the full `drm_info` output.
+- If the problem is only present sometimes: attach two files each: one created while the problem was present and one while it was absent.
+
+If the problem relates to input devices:
+
+- Attach a file containing the full `jay input show -v` output.
+- If the problem is only present sometimes: attach two files: one created while the problem was present and one while it was absent.
+
+If you know that some of this does not relate to your problem, disregard it.
