Public bug reported:
After installing 12.10 I have 2 visual issues. They look quite similar so I
will report them as one bug.
1) Sometimes a shadow right under the global menu becomes visible and gets
bigger over time. After a few seconds it disappears, just to reappear right
away.
2) Alt+Tab / Alt+^ switcher has a border that depends on the color of the
background image. For me it has a black/white flashing border that is realy
annoying. Further this flashing also appears on the launcher.
I found out that the second bug only appears if specific applications are open
and not minimized (they might be in the background, but not minimized!), the
bug appears for me while Chromium and/or Spotify is active.
I will attach 2 screenshots. 1) have a look on the middle-right side.
2. Is the border of the application switcher (it is flashing for me and not
only black)
