+/* This patch adds synchronized-updates/application-sync support in st.
+ * This will have no effect except when an application uses the synchronized-update escape
+ * sequences. With this patch nearly all cursor flicker is eliminated in tmux, and tmux detects
+ * it automatically via terminfo.
+ *
+ * Note: this patch alters st.info to promote support for extra escape sequences, which can
+ * potentially cause application misbehaviour if you do not use this patch. Try removing or
+ * commenting out the corresponding line in st.info if this is causing issues.

 /* Instead of a default X cursor, use the xterm cursor from your cursor theme.
  * You need to uncomment the corresponding line in config.mk to use the -lXcursor library
