[Bug 795995] [NEW] flash ghost in the top left corner of the screen


Public bug reported:

Binary package hint: compiz

Both in natty & oneiric, when I re-open chromium with a session containing a page with flash, I get what looks like a shadow in the top left corner of the screen, visible on all desktops. It's on top of all windows, half transparent, but with all events passing through. It stays there until i focus on the chromium tab that has this flash applet running. Maybe a re-parenting issue or something.
The ghost has exactly the same size as the flash applet.

I tried to capture this in video with gtk-record-my-desktop, but it
doesn't appear on the resulting video.

I use the nvidia-current driver.

I see this in two different computers, one 32bit the other 64bit. It
started when i moved from metacity to compiz back during the natty
cycle. It's still there in oneiric.  Those boxes have respectively a
9600GT and a GTX260.

It's 100% reproducible.

It doesn't appear with youtube (in flash mode), but with various
embedded flash videos (like on blogs).
