Bug Description
In 16.10 onwards my laptop has always shown screen tearing globally, additionally GL applications will not v-sync despite attempting to, they appear to sync slightly off from the [integrated] display.
This occurs with kernels 4.8 to 4.11 and mesa 12 to 17, so not entirely sure if it's a bug with either or a default miss-configuration in ubuntu...
ubuntu-bug also appears to be broken...

System exhibits uncontrolled screen-tearing that can be seen when moving windows, watching videos or playing games, or any graphical movement in general. The tearing gradually shifts up or down the screen, suggesting its a cycle frequency miss-match (or floating-point error).
Has affected mesa 12 and kernel 4.8 onwards.
