Hm. I mentioned at the beginning that "Problem is not affected by method i use
to achieve Vsync (driver or Kwin's one)"
This is not the case anymore. Or rather i was wrong that time. if i disable
TearFree and enable OpenGL 3.1 in kwin with vsync no problem happens. But
cursor flickers annoyingly and black boxes appears randomly on screen - mesa
bug that you mentioned? 
Also i made few roll backs to previos revisions till 15 Oct to check whether it
was a regression. Nope. TearFree always worked this way. It's me that started
using it few month ago.
