[on Fedora 40 & 41]

Hi,

I don't theme Gnome and stay with the defaults. However at some point a few months ago I must have done something that broke the theme for Qt programs: KeepassXC, QOwnNotes, Nextcloud desktop client, all rpm. I tried the flatpak version of keepassxc, no issue

symptoms:

• KeepassXC starts in light theme, even when system is using dark. If I reopen it, it switches to dark
• font became very small both in KeepassXC and QOwnnotes
• there's something wrong with the windows shadows
• taskbar icons show 3 dots instead of the apps respective icons. This is fixed with Fedora 41 for Nextcloud only
  
• taskbar icons are unresponsive/won't work. half fixed with Fedora 41.

I tried a few things:

• disabled extensions
• reset all gnome settings
• themed Qt with Kvantum (might have been a bad idea) (reverted)
• installed a custom theme for the system (reverted)
• removed some Qt stuff which seemingly weren't a dependency for anything

I also have a laptop running Fedora Gnome and don't have those issues.

What else could I try?

Thanks for reading!
