Bug Description
This SRU issue specifically resolves window animation issues caused by newer versions of mutter - later than the current version in 18.04LTS.
This SRU is part of LP: #1824229 for 18.04 & 18.10 where additional disco fixes have been backported.
For 19.04, only the animation fix has been applied (see the attached disco.debdiff)
[Impact]
* For Cosmic and Disco, animations when enabled leave visible window artifacts when various budgie window elements are opened and closed such as menu popovers and alt+tab window..
This has been reported upstream https:/
The issue is due to changes made in mutter 3.30 and later.
* The Ubuntu Desktop team for Bionic is also proposing to bring in changes in a proposed mutter release which similarly breaks Ubuntu Budgie LTS in this area. https:/
* The fix made here is to force a repaint of the window area being animated. Current testing have not shown any noticable user facing impacts such as slow/sluggish animation effects.
[Test Case]
18.04: Start from current 18.04 Ubuntu Budgie fully up-to-date.
* Open budgie-
- Open the menu 3 or 4 times. Note that the menu opens and closes correctly
- Open 3 or 4 apps. Alt+Tab. Repeat several times. No obvious window artifacts are displayed
* To upgrade budgie-desktop on 18.04 - Enable the proposed channel. Install the following packages: budgie-core budgie-desktop gir1.2-budgie-1.0 libbudgie-plugin0 libbudgietheme0 libraven0
* After a reboot and login repeat the menu opening and alt+tab actions above. Note that animations are still displayed correctly without any obvious window artifacts being displayed.
18.04 + mutter uplift: enable the proposed repository and install libmutter-2-0. Reboot.
- Open the menu 3 or 4 times. Note that the background edge of the menu remains visible on the desktop but disappears when you move your mouse over the area.
- Open 3 or 4 apps. Alt+Tab. Repeat several times. Most times (not always) the alt+tab window does not fully disappear until the mouse is moved over it.
* To upgrade budgie-desktop on 18.04 + mutter - with the proposed channel still enabled. Install the following packages: budgie-core budgie-desktop gir1.2-budgie-1.0 libbudgie-plugin0 libbudgietheme0 libraven0
* After a reboot and login repeat the menu opening and alt+tab actions above. Note that animations are displayed correctly without any obvious window artifacts being displayed.
18.10 & 19.04:
- Open the menu 3 or 4 times. Note that the background edge of the menu remains visible on the desktop but disappears when you move your mouse over the area.
- Open 3 or 4 apps. Alt+Tab. Repeat several times. Most times (not always) the alt+tab window does not fully disappear until the mouse is moved over it.
* To upgrade budgie-desktop on 18.10 & 19.04 - Enable the proposed channel. Install the following packages: budgie-core budgie-desktop gir1.2-budgie-1.0 libbudgie-plugin0 libbudgietheme0 libraven0 libbudgie-private0
* After a reboot and login repeat the menu opening and alt+tab actions above. Note that animations are displayed correctly without any obvious window artifacts being displayed.
[Regression Potential]
* The regression potential is that not every budgie animation effect passes through the code that has been patched and potentially there could be certain budgie animations that may appear "broken".
If this unlikely scenario occurs, a further SRU would be required to resolve edge cases.
Alternatively, animations can be turned-off as was currently implemented in in 18.10 & 19.04
* Testing by the team + independent testing (https:/
have not uncovered any issues. Thus we believe the risks are small.
[Other Info]
Without out this SRU, either the migration of LP: #1811900 will break budgie animations in 18.04 LTS or it will hold up the mutter migration until more discovery work is made by upstream budgie developers.
