Comment 17 for bug 1450228

I have this problem with a new computer (Skylake i5-6400T), and the problem appears to come and go over time. Aside from the blinking, scrolling is jerky, vertical patches of the window become misaligned, and windows often do not refresh when uncovered.

I switched from using the Intel video to an nVidia graphics card, and the problems did not change, therefore I do not believe this is an Intel driver issue.

I am using Kubuntu 15.10 upgraded to the 4.4 kernel.
