@llity when you raise issues please always list the version of Geany and the os and its version.

Verified on Linux Mint.

Geany only provides the `close_all`, `build` and `save_all` icons, all the others are standard system icons, in particular Geany does not provide the `close` icon.

However on some systems (eg Linux Mint) it does not use even those three Geany provided icons, but its own, so you need to complain to the system about the icons its providing, there is nothing Geany can do about it.
