this is not true (unless you have a broken dark theme). They will be colorized appropriately.

Now there is now way to set GTK icons from theme, even in chrome labs. Chrome looks out of place a bit

I migrated from google-chrome to chromium-browser specifically for Linux theme support, but it seems to have been removed again here too.

Here I've attached a screenshot from the chrome setting paqe showing the gtk+ theme being in used while sanctimoniously showing the new chrome icons in use, as well as a window with the system stock icons to show the contrast/mistake.

Yes, there was a change in behavior here. Philosophically, the GTK theme mode is a sort of crossbreed between your system theme and the Chrome default theme. For example, the tabstrip still looks like a Chrome tabstrip and not a GTK tabstrip. The buttons used to be taken from the GTK theme, but now are just colorized according to the GTK theme. Where the balance lies between what looks good, bad, Chromey or system-y is a matter of taste.

One problem with using the system buttons is that the sizing won't always work that well. I've seen configurations where the edges of the icons were cut off inside our buttons (the toolbar not  being resizable according to its fonts, contents, etc.) and I expect this would happen more frequently with the new, smaller buttons.

That said, if the overwhelming majority opinion was that we should be using GTK button icons, I wouldn't argue. However, if that were the overwhelming opinion I'd expect to have seen more activity on the bug tracker (on this bug or elsewhere) so I'm skeptical that's the case.

GTK3 has symbolic icons which are SVGs inside. Their color is defined by theme. And their size can be reshaped anyhow. https://developer.gnome.org/hig/stable/icons-and-artwork.html.en

Adding support for gtk3 symbolic icons might be nice.

+bettes@  On linux, should we use the icons that match the system theme (image in c#4)?  Or should we always use the MD icons?  Personally, I'm indifferent.

My opinion is that we should continuing doing what we do today: use the MD icons, and color them according to the gtk theme.

I don't know if Alan has an opinion or not, but historically Linux UI decisions have been made by whoever's working on Linux.

That is a reasonable compromise, and I'd agree it's the best solution.  bettes@ please shout if you have a strong opinion otherwise
