I have a new E7250 that is experiencing a variety of video problems apparently related to the GPU. In IE, with GPU enabled in the IE Advance options, the cursor will change from a hand to pointer and back with every tiny mouse movement. Video conferencing will cause the entire screen to go black then reappear about every 5 seconds. And some video streams, such as "Watch Now" on  will fail to render at all. Each of these problems seems to go away when I disable the GPU rendering in IE's Advanced options, albeit at the cost of using much slower CPU rendering and video stutter.

The machine has a Inter(R) HD Graphics 5500 Display driver, set to Digital Display DELL P2213, 1680x1050, 59Hz, driver 20.19.15.4312.  Update Driver says this version is up-to-date, but based on the last 4 digits, we thing there might be a more recent driver.

Can anyone shed light on these symptoms and a possible fix? 

Thanks,

Erik
