Screen-to-screen it appears. Problem is not reproducible when I see:
(II) ATI(0): Using XFree86 Acceleration Architecture (XAA)
Solid filled rectangles
8x8 mono pattern filled rectangles
Indirect CPU to Screen color expansion
Solid Lines
Setting up tile and stipple cache:
9 128x46 slots
after setting "XaaNoScreenToScreenCopy", and just setting
"XaaNoOffscreenPixmaps" is not enough to fix it for me. Testing was
done on depth 24/32.
