+===== GPU acceleration on the Chromium Web browser =====
+This release supports the OpenGL ES accelerated Chromium Browser.\\
+To use the acceleration, edit /etc/chromium-browser/default like this:
+<code>
+CHROMIUM_FLAGS=" --use-gl=egl --ignore-gpu-blacklist --disable-accelerated-2d-canvas --num-raster-threads=2"
+</code>
+You can see much smoother HTML rendering.
+Try this link to enjoy the Webgl on the ODROID.

+Tip: When you exit the full-screen mode, the screens goes just black from time to time.\\
+Press "Ctrl-Alt-F2" and "Ctrl-Alt-F7" as a workaround.
+**Update** \\
+If you use the latest Chromium Ver 43 or higher, the hardware acceleration doesn't work if you don't enable it manually. \\
+Enter this in the URL box of the Chromium. <code>chrome://settings/</code>
+And click "Show advanced settings..." in the bottom side.  \\
+Check "System - Use hardware acceleration when available" and restart the Chromium.\\
+===== Slow window moving =====
+To fix this issue, you need to change the Windows Manager to metacity from openbox and reboot.
+  * menu/settings/Default applications for LXSession --> Core applications --> Windows manager --> metacity
+Note that, the metacity doesn't support the short-cut keys well.
+===== Kodi crashing when exit =====
+The Kodi(xbmc) crashes when exit.
+Workaround : Open a virtual terminal (ctrl-alt-F2) and kill it.
+  * killall -9 kodi.bin
+And return to desktop (ctrl-alt-F7)
