When I start my Ultrabook on battery mode then the graphics turns into lowest bit mode for few seconds and then again to normal. This problem started when I recently updated the Intel Graphics 4000 driver to latest version (9.18.10.3165).
I have also attached the screenshot along with it.
Is this a bug in the driver or there is any problem in my graphics setting?
Below is the specification of my ultrabook:
Dell Inspiron 14z 5423
Windows 7
3rd gen. i5
Intel Graphics 4000
