This bug was fixed in the package unity - 5.20.0-0ubuntu2
---------------
unity (5.20.0-0ubuntu2) precise; urgency=low
* Check to see if the window is supposed to have decorations instead
of the window actually being decorated when Undecorate() is called.
This fixes a regression from the previous SRU where windows opened
maximized upon login could have extra decorations (LP: #1195730)
unity (5.20.0-0ubuntu1) precise; urgency=low
* New upstream release.
- ResultRendererTile: fix a crash if row.renderer<TextureContainer*>()
is null (LP: #926658)
- Fix unity launcher vanishes when switching to mirrored displays
(LP: #991637)
- Fix window decorations being drawn when they should not be.
This fixes icaclient window "dancing" (LP: #1083186) and
hides decoration in a test case with Steam (LP: #1122478)
- [multimonitor] Dash - Opening dash or HUD on one screen removes panel
shadow on the other (LP: #892718)
- Press Alt+F1, panel’s shadow dissapear (LP: #942965)
* Cherry-pick a manual test for decorations fix

A crasher.
[Test Case]
No clear test case other than ensuring no crashes are observed.

non-existent) cases.

I was simply typing on the dash when compiz crashed.
