Selected Icons Turn Black When Window Out of Focus, Thunar 1.8.*

[ghost]

As the title says, the selected icons in Thunar 1.8.0 and 1.8.1 turn black for some reason when another window is in focus.
Doesn't happen with other themes or the original Numix theme, same for all icon sets.

Just installed nautilus. Same issue.

Did some testing and figured out what it is.
The darker I set the textbox background color, the darker the icons get when the window is out of focus.
To the point where if the textbox background is completely black, the icons and thumbnails turn completely invisible.

that looks like GTK's :backdrop but i thought it's supported only in GNOME and Cinnamon

Also, it's not just brightness that changes, but color as well.

yeah, it seems what one of backdrop values is mixed with TXT_BG (which is fine, but mix amount should be much smaller), i am now installing bspwm to try it in Xephyr (backdrop is not working in awesome or openbox)

UPD: it seems what those icons are not :backdrop - related, i'll dig more into it

Since the issue is related to the theme colors, I just tried some dark themes besides oomox, like Adwaita Dark and Arc Dark and the same thing happens apparently. The icons get darker when the window is out of focus, although it's not as noticeable since those themes are not as dark as the one I'm using.
So I guess it's not an oomox issue then..

@shimapan-mode i know for sure gtk-3 have some hardcoded widget parts not fully ruleable by themes (for example Inset/Outset/Groove/Ridge frames or some outline properties) so it could be a case

however i can't say for sure because i don't know how to introspect iconview with gtk inspector

[ghost]

@actionless yeah it's not :backdrop, it's :active, check it

Well, I suppose I'll just save that css bit in .config/gtk-3.0/gtk.css then.

thanks for helping to debug this, i've pushed a fix

since you are a gentoo user, mb you'll have a look on a ebuild? #153

[ghost]

np, I'd love to help with the ebuild, but I don't have experience writing ebuilds, and I've got exams coming up real close so I can't afford to procrastinate any longer..
I'll help out if the issue is still active after a couple of weeks
