Dash is flickering when a video playback window is underneath it

[Stepan Roucka]

This problem appeared after upgrading to Ubuntu 12.10.
Steps to reproduce:
 - Open a video in Totem or in VLC
 - Activate the dash
The part of the dash which overlaps the video is flickering (repeatedly becoming fully transparent for a fraction of a second). It doesn't matter whether the video is playing or paused. The problem remains even when the video window is hidden behind other windows.

I think the fix for bug 1070735 might solve this. Please wait and test that when it's released.

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Todor Velichkov (tosho)]

same here. even if the player is in the background (paused) and there is another application above it when I hit the Dash it flickers.

unity 6.10.0
ubuntu 12.10 x64
kernel 3.6.9

[Daniel van Vugt (vanvugt)]

The aforementioned potential fix is in Unity 6.12. Please try that (when it's available).

[Kai Mast (kai-mast)]

Same here with proprietary nvidia drivers on raring

[Stepan Roucka (rouckas)]

I still have this problem in Unity 6.12.0-0ubuntu0.2

[Stepan Roucka (rouckas)]

I confirm this bug in Raring 13.04 with
unity 7.0.0daily13.04.18~13.04-0ubuntu1
Using both opensource xserver-xorg-video-ati and proprietary fglrx-updates drivers

Sorry folks, but as part of the bug clean up ahead of 16.04 I'm marking this as invalid because it affects an Ubuntu release which is now unsupported. If you can still recreate this bug in a supported release please do open a new bug and we can triage it for consideration in the 16.04 development cycle.
