Parts of UI transparent (and have other issues) when using KDE+Kvantum transparent theme

[Moshe-Shelomov]

qBittorrent & operating system versions

OS: Endeavour OS (Arch-based linux distro) qBittorrent: v4.6.4 Qt: 6.6.2 Libtorrent: 2.0.10.0 Boost: 1.83.0 OpenSSL: 3.3.0 zlib: 1.3.1

What is the problem?

When I activate a transparent theme in KDE (with the use of Kvantum) I see some parts of UI becoming transparent and otherwise behaving weirdly (flickering, mouse pointer trail). When checked with standard Breeze theme (w/o transparency), there was no issue.

I'm usually using the version from the arch repo, however I checked whether the issue persists in the latest appimage (4.6.4) from the project's website and it does.

Running the program from terminal didn't show any clue about the issue

Steps to reproduce

1. Have KDE and kvantum manager
2. set transparent theme in kvantum
3. re-login for theming changes to take effect
4. launch qbittorrent

Additional context

I'm running KDE 6 on Wayland KDE version : 6.0.4

@Moshe-Shelomov Can you test with latest master build, provide an update if this is still happening/theme issue etc.?

I wonder if this is a graphic driver issue?
