Title:
everything is black and blinks (flashes) when using unity
Status in “unity” package in Ubuntu:
Incomplete
Bug description:
I am using Ubuntu Precise 12.04 LTS with last updates (25.10.2012) from
precise, precise-security, precise-updates, precise-proposed. My bug is some
similar for https://bugs.launchpad.net/ubuntu/+source/unity/+bug/819144
But I have not fglrx.

Xorg uses standard "intel" driver. Same result with using "vesa"
driver (with vesa I always have disappearing mouse cursor on tooltip
showing, even without unity and compiz). Unity_2D works fine of
course.
I will try to explain behavior of this bug...
1) Unity panel and upper panel renders (shows picture) fine.
2) Other desktop space often blinking (they replace each other) by 3 types of
picture:
a) simple black
b) some previous state of picture (ghost picture): I mean e.g. if you close
some window, you will still can see this window with buttons, which already are
not clickable of course.
c) current picture
3) If you move mouse cursor over desktop icons (I have many icons), it
sometimes cleans rectangles with icons, sometimes not.
4) If you move some window by mouse, part of desktop can be cleaned by
previouse position of this window and all positions while window moving. This
cleaning type is not always works too.
4) If you switches between consoles (Ctrl+Alt+F1, ..., Ctrl+Alt+F7), desktop
starts blinking as in "2)" and sometimes it stops on cleaned good desktop,
sometimes on black desktop (black except left and upper panel of cource).
5) Sometimes (e.g. while pressing Ctrl+Alt+F(1-6) and back to Ctrl+Alt+F7) I
can see thin lines of some picture (from actual or previous state of window, I
can't understand which) on black desktop.
I tryed to install different stable versions of unity and compiz (and
associated packages) with no success.
I tryed to install fresh drivers from
https://launchpad.net/~ubuntu-x-swat/+archive/x-updates with no success.
I rebooting my computer after each time of changing unity/compiz/drivers
packages.
After some time (of installation of different packages) unity start to
work normally (without black blinking) but for root only! I don't want
to be root all time which I using unity. Please, help.
Update 1:
Immediatly after login unity left panel can replaced by black too (not
always), but it's returned to normally after moving mouse over it.
I created new user to test behaviour under it. Same result: black and other
blinking.
Guest session is with black blinking too.
Update 2:
I have not anything like unclutter, synergy and quicksynergy.
Maybe this helps:
