Since the upgrade to version 4.14 I have most of the themes broken - displaying black window title bars and borders, even on default themes. Example screenshot:

The behavior is identical on most of the themes, except that some themes, like Alternate, B5, Beastie, Biz, Default-4.0, -4.2 (but not 4.4, 4.6 or 4.8!) are displayed correctly.

If this is of relevance, I'm running FreeBSD 12.1. Tried with compositing manager and without - no difference.

o ~/.gtkrc-2.0. In ~/.config/gtk-2.0 there is gtkfilechooser.ini and in gtk-3.0 there is bookmarks file. There is no settings.ini. But, not sure if this is relevant, there is this portion in /~/.config/xfce4/xfconf/xfce-perchannel-xml/xsettings.xml:

<property name="Gtk" type="empty">
    <property name="CanChangeAccels" type="bool" value="false"/>
    <property name="ColorPalette" type="string" value="black:white:gray50:red:purple:blue:light blue:green:yellow:orange:lavender:brown:goldenrod4:dodger blue:pink:light green:gray10:gray30:gray75:gray90"/>
    <property name="FontName" type="string" value="DejaVu Math TeX Gyre 9"/>
    <property name="MonospaceFontName" type="string" value="Monospace 8.5"/>
    <property name="IconSizes" type="string" value=""/>
    <property name="KeyThemeName" type="string" value=""/>
    <property name="ToolbarStyle" type="string" value="text"/>
    <property name="ToolbarIconSize" type="int" value="3"/>
    <property name="MenuImages" type="bool" value="true"/>
    <property name="ButtonImages" type="bool" value="false"/>
    <property name="MenuBarAccel" type="string" value="F10"/>
    <property name="CursorThemeName" type="string" value="Adwaita"/>
    <property name="CursorThemeSize" type="int" value="20"/>
    <property name="DecorationLayout" type="string" value="close,minimize,maximize:"/>
    <property name="IMPreeditStyle" type="string" value=""/>
    <property name="IMStatusStyle" type="string" value=""/>
    <property name="IMModule" type="string" value=""/>
  </property>

I use xfwm4 compositor. If I disable it, nothing changes, still getting those black bars. No compton.

Video card is Intel® HD Graphics 520. Using FreeBSD's drm-kmod drivers.

Thank you!
