For testing bug #633556 I scrapped my 1.18 install and all it's deps completely, also I deleted all mate/gtk2/gtk3/apps-settings. Now I started with a clean 1.16 -gtk3 install. Desktop usage seems fine, though I noticed the default clock applet does not show up in the panel. Adding it manually does not make it appear either. Same holds true for the weather applet. All the other applets can be added and work.
This issue doesn't exist on 1.18.x no matter what I try. Speculation, but seems plausible it's due to the legacy gtk2 support being dropped, and any weird bugs ended up fixed upstream.
Tested again with newly created user account, but this issue persists with gtk2. So I did a rebuild of MATE 1.16 with +gtk3. Now both applets show up correctly.

(In reply to kuzetsa from comment #3) > escalated by filing upstream bug > > https://github.com/mate-desktop/mate-applets/issues/292 upstream recommends confirming the build was done in a particular manner. (please confirm -gtk3 is used system-wide, or at least on mate & mate deps) retesting should be done before the issue gets re-opened. it's hard to mark the gentoo bug confirmed when upstream closed the issue without proof that the build was done correctly (build logs for the specific packages would be ideal) --- https://github.com/mate-desktop/mate-applets/issues/292#issuecomment-349622551 > check your build settings, in particular, check that libmateweather is actually built with the same GTK+ as mate-panel and mate-applets.
