NC14 on cloud.nextcloud.com, on Ubuntu Gnome, Firefox:
When in the files app, all app icons are shown. When I switch to the Deck app, keeping the browser size the same (filling the whole screen), two icons disappear and I see the "..." option instead.


Since all icons still require the same size, and there is enough space for them, I'd assume that all icons are shown also when selecting the Deck app.
GitMate.io thinks possibly related issues are https://github.com/nextcloud/server/issues/6075 (App Passwords not displayed ), https://github.com/nextcloud/server/issues/9514 (main menu bar), https://github.com/nextcloud/server/issues/3921 (Firefox: Icons invisible in app menu), https://github.com/nextcloud/server/issues/922 (App icons disappear when searching?), and https://github.com/nextcloud/server/pull/10787 (Fixes the app menu).

@mathiasconradt what's your resolution?
@skjnldsv Maybe related to the padding size change we did to the logo in https://github.com/nextcloud/server/pull/10838?
Why would the padding change when I select another icon though. The logo would always still have the same width.
The padding change have some influence on the calculation of the available space for the apps menu. I'll have a look into that.
@juliushaertl if you change the logo you may have a look at this, too:
This is how the logo looks like in IE11:

Curiously enough, I still have the same issue in Nextcloud 15.0.2 : only the first 9 icons are displayed, followed by the expand button, exactly like shown in the second picture of the first post above. Possible to re-open ?
