-TODO: weird flicker after changing backgorund pixmap
-   Esetroot some image
-   rxvt -ip -sh 50 -tint blue
-   Esetroot some image again
-   resizing the window now shows flashes of untinted pixmap (metacity)
-
 	- fix the issue where urxvtd would not immediately close a window
           when the command exited but only on the next X event.
         - fix the issue where making a selection in one urxvtd window
           would not clear it visually in another.
         - changed terminfo file not to use application keypad mode.
+        - fix an issue of urxvt not getting background pixmap updates
+          and flickering after bg pixmap changes.
 	- fix redraw bug in xterm scrollbar with -sr (reported by Mikachu).
         - correctly provide dependencies for libev (µikachu).
         - minor code reorganisations and cleanups.
