Laptop Display problems, External display works

[descalzo]

So my Yoga 2 Pro is working wonderfully! All the hardware seems to work (except HDMI audio out).

If I close the lid and attach a monitor, the graphics work perfectly, as far as I can tell. I even played a game of League of Legends on it (I lost).

BUT on the laptop display, some programs show up garbled. Artifacts appear. Some icons look like gray barcodes. The bottom half of the screen flickers. Google Chrome is especially bad but if I turn off Hardware Acceleration it works great. Once I hook it back up to the external display AND turn off the laptop display, though, everything is back to perfect.

I think, but do not know, that part of the problem is the QHD+ display (3200x1800)

My laptop is Lenovo Yoga 2 Pro

Graphics Intel 4400

Resolution 3200x1800

Processor i7-4510U

I have attached my SendMe files.
