right after x server startup i have very corrupted image, all gtk2 apps have no

#Option  "EXANoUploadToScreen" "1"
#Option         "EXANoComposite" "1"

has no positive effect.

------- Comment #5 from randrik at mail.ru  2007-12-23 09:21 PST -------
Ok, with 

(**) NOUVEAU(0): Option "MigrationHeuristic" "greedy"
(**) NOUVEAU(0): Option "EXANoComposite" "1"
(**) NOUVEAU(0): Option "EXANoUploadToScreen" "1"
(**) NOUVEAU(0): Option "EXANoDownloadFromScreen" "1"

it works better. Fonts are back, and window decorations sometimes fully
visible. But scroll (xchat, mozilla) still give me very strange results - image
not updated until something "forced" redraw. (i'm using e
0.16.8.11-001 as my
window manager, but it works just fine with nouveau + nv11 and nouveau + nv40)

Found workaround:

xcompmgr -a

Everything (gtk2) run fast and perfect.

with only (**) NOUVEAU(0): Option "MigrationHeuristic"
"greedy" i don't need
xcompmgr anymore. KDE apps works too.
