Just updated to 30.0.0 earlier and noticed I couldn’t see any of the icons at the top of the screen. Turns out it’s because they are now black, so they were blending in with the background, no matter what color theme I set the instance to in my appearance and accessibility settings.
The text label is also slightly misaligned; a bit too high so that they overlap a bit with the icon.
This appears to be specific to Firefox. I opened my Nextcloud in Chromium and they look fine, so whatever change was made in 30.0 only affects Firefox.
The issue with the icons staying dark and blending in also appears to be related to selecting the dark theme with the new default wallpaper. Something about the dark theme settings for that default wallpaper make the icons barely legible against that wallpaper.
