+=====
+
+Description
+-----------
+
+This patch create 32bit window in tabbed. This allows to handle windows with
+transparency
+
+Note that *you need an X composite manager* (e.g. compton, xcompmgr) to make
+this patch effective.
+
+If you want to use transparency in st with this patch, you also need to
replace
+
+
+```C
+#define USE_ARGB (alpha != OPAQUE && opt_embed == NULL)
+```
+
+by
+
+```C
+#define USE_ARGB (alpha != OPAQUE)
+```
+
+in st.c
