===== GPU acceleration on the Chromium Web browser =====

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 test 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. 

** Note ** \\
Preinstalled Chromium Ver-47 shows wrong video rendering when we play Youtube.\\
To fix the issue, you need to enable the EGL option as described in above.

===== 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)
