The indicator icon for configuring the display resolution no longer exists

probably "by design", but... wtf
When the control panel is open but hidden behind other windows or on a different virtual desktop, clicking on "Sound Settings" or "Bluetooth Settings" does not bring it to the foreground, thus confusing users.

Why can't the desktop remember that I don't want mirrored displays when I connect my laptop to the docking station?—
this bug actually can't be reproduced every time I plug in an external monitor. It's hard to tell if there's an underlying logic.
FIXED in precise or maybe in quantal
It looks like the HDMI audio output remains selected even when the output gets unplugged. As a result, the laptop does not play sound any more.
You can fix the problem by going to Sound Settings and click once on the internal audio output (which is the only output).
oneiric regression: Sometimes when I switch on the HDMI output, the sound also switches to it, but not consistently.
oneiric regression: We've lost the workspace previews in the panel. There's indicator-workspaces on Launchpad (ppa-geod), but it only shows the current desktop number.
oneiric regression: The System Load indicator doesn't start automatically on login
oneiric regression: Tray icons, including the bluetooth icon and the KTorrent icon, sometimes disappears from the panel. The icons can still be seen by opening the unity-2d-panel.—

Displays: sometimes clicking on the second monitor does not select it. After fiddling with it long enough (dragging, clicking, etc) eventually it gets selected.
Dragging windows around becomes slow and jerky after some time. OpenGL acceleration works fine, it seems like a compiz issue with the intel driver. I can easily reprodiuce this on a Thinkpad X201 (Arrandale), but it's a lot harder to trigger on a X220 (Sandybridge).—

770160: windows start to move slow after using compiz for some hours
888039: Gradual degradation in desktop performance.
891744: Dragging windows stutter during and after grid animation
Improved in Precise, but there's still high cpu usage in some cases (see bugs)
FIXED in Quantal and maybe also in Precise
When switching workspaces, focus can go to a window hidden behind another full-screen window. Compiz does not seem to remember which window previously had focus in each workspace.—

When the video mode changes, full-screen windows get shuffled to different workspaces and don't come back to their original locations when the resolution changes back. This is particularly annoying when plugging/unplugging monitors.
this is a longstanding issue with compiz
confirmed on Precise
the "Desktop Cube" plugin of Compiz makes the display flicker briefly every time I switch workspace. This happens both with a Thinkpad X201 (Arrandale) and X200s (GM45).

If I drag an icon around in Nautilus, I can often make Compiz hang after a while. Restarting Unity from the console often cures the problem.—
FIXED in Precise
While dragging icons or other objects, I can only switch workspaces by going to the left edge. It doesn't work on the right. This happens with both "Desktop Wall" and "Desktop Cube".
In precise, desktop switching works on both edges, but the screen flickers awfully
You can't abort icon dragging with the ESC key

Confirmed on Precise
When dragging a window across the edge to another desktop, the mouse cursor jumps to the left or to the right, outside of the window title.—
There's a trashcan icon on my dock that brings up a new tab in browser

Notification OSDs won't go away by clicking on them. They just become more transparent when hovering the mouse. I can reproduce it every time by typing "notify-send foo" in a terminal
long-time issue
confirmed in precise
NOTABUG: works this way by design :-(
Workaround: uninstall notify-osd and install notification-daemon
I can't configure the key to switch focus to the launcher to Super alone. I had to resort to Super-space, which is not comfortable for me
fixed in oneiric
If I edit preferences in ccsm, sometimes Unity does not pick them up until restarted
I haven't seen this in a while, it's probably fixed
When I enable or disable a plugin in ccsm, sometimes compiz hangs. If I kill it, it takes down the whole X server
The Gnome Control Center (aka System Settings) often closes when clicking on icons. I suspect it's simply crashing.—

Evolution 3: the (webkit based) mail preview pane sometimes "crashes". It remains blank or garbled and there's no way to restore it until I restart the application.—

Evolution 3: sometimes Evolution hangs on shutdown until I kill it from the terminal
Evolution 3: this might sound like a rant, but due to many other stability issues with Evolution, my email experience has become really miserable in Oneiric.—
When I connect a monitor to the DisplayPort output, sometimes the sound output also switches to it (but sometimes it doesn't, I couldn't figure out why). The sound output setting is buried deep into Control Panel / Sound Settings / Hardware / Profile, so it took me a while to figure out what had happened the first time.
If I unplug AC while the lid is closed, the laptop does not automatically suspend. This is very dangerous because you can accidentally store your laptop in a backpack while it's still running.
Wifi becomes incredibly slow after a few minutes of use (like, 1-2kb/s). This is a an Intel iwlagn 6250. I tried all kernels all the way to 3.2 with no improvement. The only workaround I could find is disabling 802.11n support.—
My jWin Bluetooth headphones stop working when there's no sound output for about 30 seconds. After this, all applications that try to play some sound will hang until I disconnect the bluetooth device
Fixed in kernel 3.2
The Bluetooth headphones don't get automatically reconnected when I turn them on. Clicking on Connect in the control panel seems to work for one second, then it fails. The only way to reconnect is removing the device and then paring it again.
After upgrading to Oneiric, the machine became unbootable due to an incomplete /run migration. There's a bug in Launchpad, but it's not getting any attention.—
breaks boot
Maybe fixed in Precise
My home is dm-crypt encrypted, alghough not with luks. After upgrading to Oneiric, it was no longer being mounted because mount thought it was of type minixfs. WTF?? To fix this, I had to pass '-n nominix' to blkid in /lib/cryptsetup/checks/un_blkid. This filtering was present in an earlier version of cryptsetup, but it has been removed in 2:1.1.3-1.

On my x200s, something goes wrong when initramfs tries to switch to the root filesystem. Due to a race with udev, some files cannot be deleted in the tmpfs
