Problems with tray icons in mate panel

[philipzae]

When resizing the mate panel in Linux Mint Mate from its default of 24 pixels in height, the network and volume icons dont look nice when the mate panel is between 25px and 31px. The network icon takes the icon 32px icon and scales it down, while the volume icon takes the 24px icon and scales it up.

Similar problems happen with the bluetooth and battery icons.

This issue has been reported in mate-panel and they suggested it also be posted here.

Someone pointed this out in IRC. This is due partially to the way icon themes are designed to work. The 16px-24px sizes are meant mostly for use on things like panels, toolbars, and buttons while 32px and up are meant for things like docks and app launchers(think mint menu). That's one of the reasons you see the change in style. The other is the very limited about of pixels you have to work with at the small sizes.

At some point this stuff needs to get cleaned up in the icon theme because it causes issues when you throw hidpi support into the mix and I would assume Mate will support it at some point.

Can't the panel use vector graphics for non-standard sizes like 25-31px if they're available?

I guess this is fixed in 1.4.3?
