I tried them one by one, and will note my observations.
XaaNoScreenToScreenCopy: Shifting windows seems a bit better, but not much.
Still some artifacts. Fonts still not good. Moving windows slow.
XaaNoScanlineCPUToScreenColorExpandFill: Fonts OK now.
Moving windows still artifacts.
XaaNoPixmapCache: No positive effects
XaaNoOffscreenPixmaps: No positive effects
XaaNoMono8x8PatternFillRect: No positive effects.
XaaNoSolidFillRect: No positive effects.
As none of these alone cures all problems, I repeated the test with all
options enabled, then remove one by one until problems re-appear.
All options enabled: same result as the combined results of
XaaNoScreenToScreenCopy and XaaNoScanlineCPUToScreenColorExpandFill: XTerm
fonts OK, shifting windows better, but not perfect, and slow.
Didn't trust my memory, so tried again with only option NoAccel.
All problems gone, and shifting windows seems faster than with Option
XaaNoScreenToScreenCopy.

Intel Celeron 466, XFree 4.2.0, i810 chipset, Gentoo Linux.
ATI Technologies Inc 3D Rage IIC 215IIC [Mach64 GT IIC] (rev 58).
If it helps, I can do another compile and see what options were set, because
Gentoo is a 'compile-it-yourself' distribution where options are tailored to
the system you run it on.
