Is black background under launchers icon expected ?

[Coeur-Noir]

Hi,

using blur-my-shell v61 under Ubuntu 24.04 ( gnome 46 ),
enabled for dash, top panel and app-view.

In app-view, app-folders are set to « no theme » as well as « shell components ».

I did not expect icons for single launchers to show a black background :

App-folders are correctly themed on that view, but their background turn black once opened.

I expect no background / transparent background for « single » launchers items ( ie. Bureau, clapper, Logiciels… ) and the same dark-grey for background in opened app-folders.

Don't know if it's an issue with blur-my-shell extension itself OR maybe Yaru-theme used by Ubuntu 24.04
BUT it doesn't happen like this in Ubuntu 22.04 ( where launchers backgrounds are transparent and opened app-folders keep dark-grey background. )

Best regards.

Hello, thanks for opening this issue. This is technically related to blur-my-shell (not yaru), but is what is intended:

• no theme for shell components means that I don't even try to apply any theming to the dash, the search results, the appfolder icons, the application icons... So it is normal, if you have selected this option, to have grey component as it is the color yaru chose. The behaviour changed a bit with the GNOME 46 update as I had to change a lot of styling for this update, but the differences are only "incidentals" and related to yaru in the sense that theme should not have been changed when using original gnome theme
• no theme for appfolders means that the "opened" appfolder still has its original background, which is with the default theme a grey one (as well as with yaru, I guess). So maybe this is what you want to disable if I understood correctly?

So this behaviour is expected, and I know it is not perfect because you would probably want to have different behaviour for the different components of the overview, but at this point it is probably better to adapt the gnome-shell theme itself to that because blur-my-shell has this option only for "regular" users not to have to tweak their theme for blur to be shown. But tell me if you have a precise idea of something to change here!

Hello, and thanks for attention ;-)

Actually color seems correct, there are 2 hues of blackish~grey in Yaru theme for background.
So no problem with app-folders background when opened.

I just wonder if the darkest background for single launchers is a good idea, I was expecting … none, just transparent background, as in 22.04. After all it's maybe just a matter of habit ;-)

A solid background for single launcher is probably better for readability BUT then it's a lesser visual difference between app-folders and single items.

Anyway we can't say it's a bug, it's not. Maybe some room for improvement ? Like some transparency for the solid darkest background of single launchers ?

Or maybe easier : just switch the two kinds of backgrounds, the darkest for app-folders ( which need more contrast because of the many colored icons + will graciously fade in with the already darkest background of once-opened app-folder ) and therefore the less dark background for single launchers ( wich need less contrast as they only show one less colored icon. )

Here is a comparative picture of actual 22.04 and 24.04 :

Thank you !
