Problem installing and several glitches

[Cris70]

Thank you for the great Ant-Dark kde theme! However, on plasma 6, I cannot install it. I get the error: Installation of /tmp/SriDJF-Ant-Dark.tar.gz failed: Could not install dependency: 'kns://plasma-themes.knsrc/api.kde-look.org/1464321'

I resorted to installing all the single parts manually, but I have several glitches:

• Graphical glitch with curved panels (especially visible on light background):
  
  
• Dark icons on dark panels:
  
• Wrong icons for arrows (look at the first three items from the left in the Dolphin toolbar):
  
• Bluetooth icon in the tray show a generic icon instead:
  
• Dolphin shows normal icons when I browse folder, until I browse the Home folder... as soon as I browse the Home folder, symbols appear on the lower left corner of all the icons, and they persist even if I browse to other folders:
  
  Symbols go away if I close and reopen Dolphin, but they appear again as soon as I browse to the home directory.
• Spectacle has transparent background (should be blurred at least, but it is completely transparent instead)
• Dolphin vertically cuts disk usage statistics in its status bar:
  

I'm using openSUSE Tumbleweed with KDE Plasma 6:

Can you help?
Thank you in advance!
