Kvantum VS qbittorrent

I'm using Kvantum engine with my custom Andromeda theme

I think Kvantum has support for theming both Qt6 and Qt5 apps now though so that might be worth trying if it bothers you that much.

The ones I know of are: Aurorae (built-in one), Kvantum (https://github.com/tsujan/Kvantum/tree/master/Kvantum) and Lightly (just a theme https://github.com/Luwx/Lightly). store.kde.org is down (at least I can't access it at the moment), so I've shared github links.

What about : https://github.com/tsujan/Kvantum ?

Make sure Kvantum is selected in the application style section of your look and feel settings. Read through the usage instructions on the Kvantum GitHub page.

Perhaps you can submit an issue

As for Kvantum, you'll need to either install it from your distro's repos if you're lucky, or if not you'll need to compile it yourself, you can check how to do that here.

arc-theme with kvantum look petty good imo.

It's written in QT, so you need a QT theme. There's the KvLibadwaita style for the Kvantum theme engine.

Not orange bars, but the Dracula qbittorrent theme has a very visible lighter blue progress bar https://draculatheme.com/qbittorrent

A new, albeit experimental, bittorrent client has been added, qBittorrent 4.6.0, and replaced the previous "XD" client. This version had to be compiled from source, with a PR #18845 to fix the peer list (i2p peers not showing). To make qBittorrent work, latest libtorrent had to be compiled from source, too. Commits used to compile both qBittorrent and libtorrent are listed in the changelog. A dark theme (Dracula) is used by default, it wasn't looking nice in light theme, but you can always change between them in the settings.

try Dracula theme

i used this theme and the problem vanished so yeah

https://draculatheme.com/qbittorrent maybe not sure
