Launcher - Quicklists don’t have active blur

Bug Description

Hi, if I play some video the background of jumplist doesn't change

To Reproduce:

1. Start playing a video on the left side of the screen
2. Open a quicklist on top of the video

What currently incorrectly happens:
- The image from the moment the quicklist was opened is 'frozen' into the quiclist

Correct desired behaviour:
- it should be possible to see the playing video through the transparent background of the quicklist.

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

I realized this some time ago too, not sure if this is really a bug or a wishlist-improvement...

The new Launcher tooltips suffer the same problem.

For tooltips, this bug is fixed by my fix for bug 988079: lp:~vanvugt/unity/regionalDamage

Not yet sure why it doesn't also fix quicklists.

Hmm, I don't think its really "fixed" by that branch, rather just the
tooltip is being re-rendered completely all the time every time there's
damage underneath it. That still constitutes the usage of
glCopyTexSubImage2D and not doing active blur properly using framebuffer
objects I would think.

I think doing those small blurs in software is proving to be faster than in hardware right now. Certainly I don't see any slowdown redrawing the tooltips this way, but do get a significant slowdown when other /proper/ active blurs are updating.

There will be no slowdown once we merge gles and fbo binds are done just
after glXSwapBuffers

Splitting this bug in two:

Bug 873387 is for quicklists.
Bug 967112 is for tooltips.

Fix committed into lp:unity at revision None, scheduled for release in unity, milestone 7.1.1

This bug was fixed in the package unity - 7.1.0+13.10.20130920-0ubuntu1

---------------
unity (7.1.0+13.10.20130920-0ubuntu1) saucy; urgency=low

[ Stephen M. Webb ]
* render the Dash frame all the way to the bottom of the screen (lp:
#1100120). (LP: #1100120)

[ Brandon Schaefer ]
* Ignore mouse movements if the mouse starts over a switcher icon.
Clicking still works fine, we just wont steal focus from the alt+tab
work. (LP: #1215630)
* Make sure we ignore mouse movement over detail icons if the mouse
starts over it at start. Let the mouse take selection control once
it moves outside of any icon, vs having to enter a different icon.
(LP: #1223037, #1223039)
* Add an option to disable the mouse in the switcher. (LP: #1224048)
* When the shortcut is open, and we receive a ButtonPress or KeyPress
hide it. As this causes problems else where, and it really should
close if the user attempts to do anything (even while holding
super!). (LP: #932718)
* Set an upper bound on the amount of icons we go through to check
tooltips. As the accordion effect was causing the mouse to go
through the icons to fast, making the test fail.
* Make sure we move the mouse over the target icon while we are
dragging the source icon.
* Get the real shortcut to activate ibus. (LP: #1227056)
* Only accept focus if the mouse moves in 3 directions on switcher
start up if the mouse starts over the switcher window. This is an
attempt to tell the difference between a bump and intentional
movement. (LP: #1223630)

[ Marco Trevisan (Treviño) ]
* DesktopApplicationManager: added new app manager layer so that we
can emit app events.
* Application: add desktop_id method, and implement in
desktop::Application.
* Launcher: only fade the launcher when in auto-hide and dash is
opened. (LP: #1223979, #1044926)
* ApplicationLauncherIcon: log unity zeitgeist events on stick,
unstick, removal and delete. (LP: #779449)
* UnityScreen: add support for Super+Arrows shortcuts to manage the
focused window Super+Arrows shortcut allows to move and maximize /
restore / minimize the focused window on the screen. (LP: #992697,
#751050)
* Launcher: use nux::Animation for all the launcher animations This
allows to do these when compiz requests to prepare painting, instead
of using only an idle to perform this. (LP: #1226114, #1224766)
* ShortcutView: use StaticCairoText instead of StaticText for
rendering the View Improves the text alignment and visual quality.
* UnityShell: redraw the dash also if a non-blurred area is damaged If
the dash is damaged, but not the blurred area, it won't redraw. We
need to draw it, in order to avoid flickering of its border. Also,
add the redraw_view_if_damaged utility function to redraw a view if
really needed. (LP: #1224340)
* AnimationUtils: add utility functions to handle nux::Animation's
start and reversion Update the whole code using nux::animation to
use these facility functions.
* Launcher: fix style to use postfixed-underscore for private members
Also remove some tabs and useless members.
* ...

Fix Released in Nux Unity 7.1.1.
