Headers of columns have unnecessary margin between theirs text and right edge

[GitHubinatrix]

qBittorrent & operating system versions

qBittorrent: 4.6.2 x64
Operating system: Windows 10 Enterprise 20H2 x64
Qt: 6.4.3
Libtorrent: 1.2.19.0
Boost: 1.83.0
OpenSSL: 1.1.1w
zlib: 1.3

What is the problem?

All names of columns on their right side have a profound empty space that causes left sides to be obscured. I can of course widen those truncated headers - but I do not want to be forced to scroll horizontally the main window

This has been like so in my qBittorrent as far as before version 4.5.2

Additional context

I run with

Windows Settings > Settings > Ease Of Access > Display > Make everything bigger > Change the size of apps and text on the main display > 150%

but changing it to default 100% does not make this issue go away

I have completely forgotten that my qBittorrent looks like it looks because of a theme

Default theme and some other ones do not have this issue; although I did just now found another one with the same problem

All in all, this is most likely not a bug of qBittorent itself but some mistake done within theme[s] - and already has been reported here: jagannatharjun/qbt-theme#73
