#675 Peazip has Wayland generic icon on Wayland session of KDE Plasma desktop environemnt

[Strangiato]

Hi

I have Qt5 version of Peazip 8.5.0 installed on a linux distribution runnijng Wayland session
of KDE Plasma desktop environment. As we can see in the attached screenshot, Peazip
has a Wayland generic icon instead of its own icon. I also see the Wayland generic icon
in alt+tab menu.
Possibly the following link can help you to fix this issue.
