 +===== 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:
 +CHROMIUM_FLAGS="​ --use-gl=egl --ignore-gpu-blacklist --disable-accelerated-2d-canvas --num-raster-threads=2"​
 +You can see much smoother HTML rendering.

 +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)
