Are you using a compositor like compiz or metacity or kwim?  3D and composite don't work well together with DRI1.  DRI2 fixes this, but requires KMS.

Is this a regression and if so, when was the last time it worked correctly?

How to distinguish it?

I'm using metacity w/ /apps/metacity/general/compositing_manager. I'll try without.

No. It is not a regression.

Are elements of the GUI blinking or is the entire monitor blinking (i.e., going in and out of powersave mode)?

This is expected with 3D and compositing under DRI1.

GUI blinking, In 'normal' work I have similar problems when I move laptop and I thought that connection cables started not to connect (if this is the case the 'normal work blinking' is a regression).

Disabling compositing fixed the problem.

This sounds like the cable is coming loose if it only happens when you move the laptop.

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.
