Thank's to confirm leo !

none of the ones that were on 2880 + none of new downloaded on other versions

Yes it does change in the opera://gpu to :

Graphics Feature Status
Canvas: Hardware accelerated
CheckerImaging: Enabled
Flash: Hardware accelerated
Flash Stage3D: Hardware accelerated
Flash Stage3D Baseline profile: Hardware accelerated
Compositing: Hardware accelerated
Multiple Raster Threads: Enabled
Native GpuMemoryBuffers: Hardware accelerated
Rasterization: Hardware accelerated
Video Decode: Hardware accelerated
WebGL: Hardware accelerated
WebGL2: Hardware accelerated

Thank's leo for comment.

Regardless if activated or not, wallpaper remain frozen.

I have checked in the change log after 2880 for related info to no luck

Maybe because i'm on arch ( using package build from aur ).
The original package is deb which seem to install stuff in /opt, where arch ( aur ) install in /usr/lib

As you can see, hardware acceleration is disabled or not working in your system. Check if it's enabled in settings.

I am having difficulties with my animated wallpaper.

The last working version with animated wallpaper is : 53.0.2880.
Tried on versions : 2893, 2900, 2906 ( frozen wallpaper )

Thank's

@deluxive thanks for analysis of 1Password. I've sent them request to update their signatures database with our new certificate. As for the crash build 53.0.2900.0 release this week includes fix for crash when opening new tabs on Mac. Hopefully it should also be fine for you.

1password issue is still not resolved. 1password support told me they have not been officially contacted by opera developers (https://discussions.agilebits.com/discussion/comment/419030#Comment_419030). Can the developers contact 1password at support@agilebits.com to have this resolved? Thanks!

The change log, and the announcement.

"We’ve fixed animations on the Speed Dial page, so drag’n’drop operation of tiles should be smooth again."

Some of the other changes:
- DNA-66695 Move common/html_reader to desktop/common/utility.
- DNA-68591 Move OperaBrowserMainPartsWin out of desktop/common.
- DNA-68620 Create prefs for category, and language selection."

The change log, and the announcement.

"Before the weekend comes, we’ve prepared for you a developer update containing some design improvements. Also, we corrected the German translation for the arrow tool in snapshot.

Known issues:
- Speed Dial extensions have empty tiles.
- Opera doesn’t run on macOS 10.10."

The Chromium is updated to version 66.0.3359.27.

The change log, and the announcement.

"Since spring is just around the corner, we’re doing some spring cleaning in Opera developer 53. You’ll find improvements to tabs’ display, especially with several of them opened, and some new colors for the address bar in this build.

 
Optimized display of tabs

Recently, for Mac users, it’s been difficult to find and manage a particular tab when many of them are open. We figured out a way to optimize this and make your plentiful tabs’ favicons more visible. Let’s see how it changed:

 
To make it even more visible, clicking on a tab will expand it to make it easier to manage.

 
There is also a fresh, sharpened coloring done to the address bar.

Other highlights:
- Windows 10 bug with an empty pop-up, when text is selected by a touch screen is fixed.
- Opera will install on Ubuntu 18.04, Bionic.
- Touch bar is fixed (macOS).
- Missing translations added."

Known issues:

- Tabs previews can be broken.
- Capturing full page by Snapshot doesn’t work.
- Issues with saving as PDF..

The Chromium has been updated to version 66.0.3355.4.

@rudrick Although they seem very interesting, I don't see them coming in a near future.

Sad news.

Workaround for me, i edit the $HOME/.local/share/applications/exo-web-browser.desktop

English:

Failed to execute default Web Browser.
Input/output error

Site opens, but with the stupid system dialog.

No dialog with Opera developer 53.0.2880.0, Opera stable, Firefox, Vivaldi
The dialog only opens if Opera Dev ⋝ 53.0.2885.0 is the default browser.
command line:
exo-open URL with dialog (exo-open starts the default browser)
opera-developer URL without dialog

OS: Siduction 64bit

Can anybody confirm that, or what is the mistake?

The change log, and the announcement.

"Here are some things worth mentioning:
- "Easy Setup" layout has been polished.
- The crash, when switching between tabs is fixed.
- Spinner, and mute icons have been properly scaled for DPI > 225%."
