Tooltips backgrounds are not refreshed (no active blur)

Bug Description

[Test Case]
1) choose a solid black color for the Desktop Background to get a better effect
2) open some program that has a good contrast to the desktop background
3) mouseover any of the unity icons in the launcher to show the tooltip
4) while the tooltip is shown press Super+ALT+D to show the Desktop
-> Verify that the background of the tooltip 'matches' the one on the desktop

[Regression Potential]
Visual regressions, shell drawing problems. Big change, many regression potentials.

Original description:

When A Unity Launcher Tooltip is shown and you press STRG+ALT+D to show the Desktop the half-transparent Background of the Tooltip does not update. Either it doesnt use true transparency or this is a bug.

to reproduce this use the following steps:

1) choose a dark wallpaper or solid black color for the Desktop Background to get a better effect

2) open some program that has a good contrast to the desktop background (website, filemanager or office programm if a dark wallpaper is set

3) mouseover any of the unity icons in the launcher to show the tooltip

4) while the tooltip is shown press STRG+ALT+D to show the Desktop

You will see that the Background of the tooltip is not updated to match the Desktop. I don't know if this is intended but it may be a bug if this was supposed to be true transparency in Unity 3D

The issue is a bit similar to bug #873387, fixing the other one would fix this one as well

I'm making this bug just about tooltips. Bug 873387 can be about quicklists.

Hello Sven, or anyone else affected,

Accepted unity into precise-proposed. The package will build now and be available at http://launchpad.net/ubuntu/+source/unity/5.16.0-0ubuntu1 in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please change the bug tag from verification-needed to verification-done. If it does not, change the tag to verification-failed. In either case, details of your testing will help us make a better decision.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance!

Just for the record and other testers:

Its supposed to be CTRL+SUPER+D to show the desktop if i recall correctly. If anyone can edit this please do.
I must have messed that up and i even wrote the german "STRG" instead of CTRL ...

thx for pushing the fix to proposed :-)

Works wonderfully. No regressions seen, the behavior is spot-on now.

Unfortunately not so good in quantal --> bug 1036572
