[Bug 101229] Global screen tearing (scrolling, Hz miss-match?)

To prevent tearing, you need to either choose OpenGL instead of XRender and an appropriate tearing prevention setting, or enable TearFree with

xrandr --output eDP --set TearFree on

it's less obvious, but there still appears to be screen tearing when running via openGL 3.1 using full-screen-repaints.

It's also reasonably obvious that for some GUIs their buttons will update their two triangles across two frames instead of one, this seems to be a much rarer occurrence with the above settings however.
