You misunderstood me.
1. Such blinking occures when I move laptop and I assume somthing is loose.
However it occured few times so it might be coincidence (I first observed it
and after some time I observed 2) )
2. Such blinking started to occure when laptop is still which may be 1) or
somehow 3)
3. Such blinking occures at specific moment (after loading ufo:ai). In this
case it is rather not loose cable as laptop is still and it is reproducable.
Also disabling composition fixs it. Laptop was still

So I can have:
1. Software bug which due to few correlations seemed to be hardware bug
2. Hardware bug which is turned on by some GPU commends. However it seems
unlikely for me.
3. Software and hardware bug which looks the same, Hardware occures when laptop
is moved and software when composition is enabled.
