[Bug]: NC 34.0.0 - app icons rendered inline with hardcoded fill:#fff, invisible on light theme (apps management list, user menu)

[martinlb]

⚠️ This issue respects the following points: ⚠️

• This is a bug, not a question or a configuration/webserver/proxy issue.
• This issue is not already reported on Github OR Nextcloud Community Forum (I've searched it).
• Nextcloud Server is up to date. See Maintenance and Release Schedule for supported versions.
• I agree to follow Nextcloud's Code of Conduct.

Bug description

On Nextcloud 34.0.0 (Hub 26 Spring), several app icons are invisible on the light theme in:

• the apps management list (Settings → Apps): e.g. Activity, AppAPI, Bookmarks, Calendar, Contacts, Deck
• the user menu: the "Apps" entry icon

Inspecting an invisible icon shows the SVG is rendered inline with a hardcoded style="fill:#fff" on the <path>, and no CSS inversion filter applied (filter: none computed). White fill on a light background → invisible (only barely visible on hover thanks to the darker row background).

Example (Calendar icon in Settings → Apps):

​html <span data-v-aaedb1c3=""><svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 32 32" ...> <path d="M5 22c-.55 0..." style="fill:#fff;fill-rule:nonzero" transform="matrix(1.4 0 0 1.4 -.8 -.8)"></path> </svg></span> ​

Other icons in the same list (Auditing/Logging, Comments, Cookbook, Cospend…) are rendered black and display fine on light theme.

Switching to the dark theme makes the white icons visible (white on dark), which confirms the fill color is fixed server-side instead of following the active theme.

But the apps icon is dark now :

Steps to reproduce

1. Run Nextcloud 34.0.0 with the light theme
2. Open Settings => Apps (or the user menu)
3. Observe missing icons (Activity, Calendar, Contacts, Deck, Bookmarks, AppAPI, "Apps" menu entry…)

Expected behavior

Icons should be recolored according to the active theme (dark on light backgrounds), or an inversion filter should be applied.

Additional info

OS : Synology DSM 7.3.2-86009 Update 3, DS920+
Note: non-stock ImageMagick/imagick setup on my Synology (manually enabled imagick for PHP 8.4 CLI + relaxed MVG coder policy in /etc/ImageMagick-6/policy.xml). Likely unrelated, as imagick should only affect favicon/touch-icon generation, not inline SVG rendering.

I don't understand how this can make it into an official non beta release.

Same issue.
