I think regressions should be treated with top priority.

i have to face two important regressions since Ubuntu 7.04 :

1°) defects concerning image rendering
My video card is an ATI Radeon 8500 LE (R200) which is not rare stuff.

a) Compiz is activated since Ubuntu 7.10. Since then i have that bug

b) Since Ubuntu 8.04 i have that bug also

Therefore switching from Ubuntu 7.04 to Ubuntu 8.04 creates is an
important regression in image rendering (bugs a + b)

2°) Photo Import from Canon IXUS 30/Powershot SD200 failed since Ubuntu 7.10
see that bug report

Considering my hardware components (ATI R200 and Canon camera) which
are not rare, that makes a lot of regressions since Ubuntu 7.04 (bugs
1a + 1b + 2)...

Please, note that there is a workaround concerning bug 1

bug 1° a) disapears if i switch to metacity with composite
(gconftool-2 -s --type bool /apps/metacity/general/compositing_manager true)

bug 1° b) disapears if i add in my xorg.conf : Option "AccelMethod" "EXA"
but it creates another bug that is solved if i add also Option
"MigrationHeuristic" "greedy"

Therefore, switching to metacity with composite and adding Option
"AccelMethod" "EXA" & Option "MigrationHeuristic" "greedy" completly
solves bug 1 a+b

Maybe that should be default settings for R200 ?

But i don't have any workaround for the camera bug, therefore i don't
know what to with my pictures :-(
I'd be please to wait for a fix but i'd like to be sure that someone
is working on it
