Close vmware horizon client.
open terminal

vi /usr/share/applications/vmware-view.desktop

Exec=vmware-view %u

Change it to:

Exec=env GTK_THEME=Yaru-light vmware-view %u

save

Restart app and now you should be able to view everything properly.

If you don’t have Yaru-light as a theme you may need to change it to what ever your OS light theme is named.

EDIT:

System versions

Horizon Client version: 2111 / build: 8.4.0
KDE Neon / Ubuntu 20.04 Linux kernel 5.15.22-xanmod1
KDE Plasma 5.24.1
Qt Vesrion 5.13.3

KDE Plasma 5.24 is out and (as we’ve come to expect) it is chock full of performance improvements, user interface refinements, and even a few handy new features.

In this post I run through the most notable and noticeable changes shipping in KDE Plasma 5.24, plus tell you how you can try the release out first hand.

While we’re on the subject: if you’re a fan of KDE Plasma and you want to see more coverage of the DE on omg! do let me know in the comments. While Plasma is not a desktop environment I’m super familiar with (thus I don’t know my way around it very well) its ballooning popularity —even the Steam Deck uses it, well kinda— has me intrigued!
