gtk dialog boxes are not consistent across linux system

Using the default options on my system, my dialog boxes don’t render correctly using Libreoffice. Here’s a gallery with a bunch of examples. Here’s a quick example of what I mean:

Gimp’s save dialog:

Libreoffices’s save dialog:

I can improve it slightly with SAL_USE_VCLPLUGIN=gtk:

Here’s a matching post on the arch linux forums where I don’t have a response yet. The above is using the vimix-light theme, though similar behavior occurs for oomox-built and flat plat blue themes. Adwaita appears to be consistent across applications.

$ libreoffice --version
LibreOffice 20m0(Build:2)

whats your problem with this? Maybe you should adjust your global (=systemwide) theme settings?

@plgeek I missed this response – sorry about that. My problem is the non-uniformity of the themes, as well as the difficulty of seeing the buttons when the theme looks fine with other applications. I’ll happily adjust “global theme settings” if you can point me in the right direction. What would cause LO to behave differently than any other application on my system? What global setting should I be taking a look at?
