 ** DONE [#B] Add dwm-center to center certain windows when opened in floating
 * DWM - Reference
+** give dwmsystray a class so picom can identify it

+
+may have something for you, at least some preliminary testing suggests that it works.
+
+In the clientmessage function in dwm.c lives the code where new client windows are embedded in the systray window.
+
+Try adding this before the XReparentWindow line:
+
+            XClassHint ch = {"dwmsystray", "dwmsystray"};
+            XSetClassHint(dpy, c->win, &ch);
+
+then add
+
+    "class_g = 'dwmsystray'",
+
+to the shadow-exclude setting in your picom.conf.
+
+You can set it to "dwm" if you want. I just chose something else in order to be able to differentiate between the bar window and the systray window.
