screen corruption when drawing buffers to screen

[karl anliot]

in 12.10 i notice screen corruption when using several applications: xaos and gpicview
with older fglrx drivers this problem does not exist.

looks like a hardware draw from a buffer is reading from bad locations in memory.

The graphic corruption disappears at lower zoom ratios.
