Probably the same issue than:

Trees in Left 4 Dead 2 have some rendering issue when you move, so in fact they
looks like to blink. See the screenshots attached.
This hits my RV770 (HD4850) and CYPRESS (HD5850).
When R600_DEBUG=nohyperz is set, there is no problem.
R600_DEBUG=nosb doesn't fix.
First bad commit is:
r600g: defer shader variant selection and depending state updates

Note that the bug happens in L4D2 only when the option "Effects details" in the
graphic options of the game is set to Medium or High, but not when set to Low.</pre>
