I tried the same thing. I'm running ubuntu 10.10 64bit. i compiled my patched
wine 1.3.7 in a 32bit ubuntu vmware box and then copied it to host. It runs
fine and the DIB engine seems to be working. I tried running regedit or winecfg
with WINEDIB=ON and i get typical "err:dibdrv:" errors which i presume means
that the DIB engine is working. Fl studio 9 demo works just fine with
WINEDIB=ON but i see no changes in performance, the gui still slows to a crawl
if i open the piano roll.
Strangely, i don't get any DIB related errors while running FL studio.
Here's my output:

WINEDIB=ON has no effect on the contents of the output.
Is it possible that FL studio simply doesn't use the DIB engine? Am i doing
something wrong here?
