You may have found that VMware workstation/player is not following the GTK theme that you’ve set, looking like this
This is due to VMware loading the outdated GTK 3.14 library bundled with it instead of the system’s GTK 3.24.
The workaround is navigating to /usr/lib/vmware/lib/ and removing/renaming these 5 folders (kudos berolinux for the hint):
libpango-1.0.so.0
libpangocairo-1.0.so.0
libpangoft2-1.0.so.0
libgtk-3.so.0
libgdk-3.so.0
“Also remove or rename /usr/lib/vmware/libconf/etc/gtk-3.0/gschemas.compiled so that VMware doesn’t crash upon opening a file dialog”
VMware will now respect your theming
