Laucher background not blurred when Dash is opened

[Sami Jaktholm]

The launcher background is occasionally left without blur (see attached screenshot). This is a regression after updating unity from version 6.2.0-0ubuntu4 to 6.4.0-0ubuntu1.

Steps to reproduce:
Make sure that launcher is set to autohide and it's not visible.
1. Open dash pressing Super
2. Notice that the launcher background is not blurred.

This happens only when dash is opened pressing Super button. If launcher happens to be visible prior to opening dash, for example opening dash from BFB, the launcher background is blurred properly. If you open dash by using lens shortcuts (Super+F for example), the launcher background is blurred correctly most of the time.

Also, if the launcher background has no blur and you click something with your mouse inside dash, the launcher background gets blurred.

I think this is somehow related to bug 1044926 because the launcher background is never blurred if the dash is shown before the launcher.

[Omer Akram (om26er)]

thanks for the bug report. Can you please run 'unity --reset' in terminal the test and let us know if the issue is still there.

[Sami Jaktholm (sjakthol)]

This bug still occurs after running unity --reset. Also tested with guest session and current daily-live ISO and the bug appears there too.

[Omer Akram (om26er)]

please paste the result of '/usr/lib/nux/unity_support_test -p' in this bug report.

[Omer Akram (om26er)]

It could be specific to ATI, or a certain class of GPUs since I can't reproduce it on SandyBridge. will test it on a netbook.

[Omer Akram (om26er)]

I can't reproduce the bug since I don't have ATI but since you can, I'll leave this one to NEW for now. Maybe someone else can reproduce the bug.

[Bilal Akhtar (bilalakhtar)]

I'm not able to reproduce this either, Intel GPU. Seems ATI-only, yeah.

[Brandon Schaefer (brandontschaefer)]

Right Im getting this on an intel chip (but not all the time). It helps when I try to go from the Hud -> Dash. Seems a logical check, or a ubus message to slow/fast.... but this is confirmed.

[Brandon Schaefer (brandontschaefer)]

Also make sure you have your launcher set to autohide....

[Brandon Schaefer (brandontschaefer)]

Now I can't reproduce this... this might have accidentally been fixed with some blur changes that went on, if anyone can reproduce this in the mean time please make a comment!

[Launchpad Janitor (janitor)]

[Expired for unity (Ubuntu) because there has been no activity for 60 days.]

[Christopher Townsend (townsend)]

This seems fixed as no new activity has occurred for this bug in some time. I also cannot reproduce, albeit, on an Intel graphics machine. Going to mark it Fixed Released. We can either reopen this bug or submit a new bug report if it still occurs for anyone.
