Taskbar icon missing on Kubuntu 14.04

[ValentinH]

There is an empty icon in the taskbar that can be clicked to access the settings.

I've got only one assumption that the reason was the size of the icon, so I resized it to 64x64.

Please try v0.3.0

[ewnd9]

Oh, I've just realised that you have the light taskbar background and the icon itself is white. I'm gonna try to add some borders to make it visible

Icon was updated in 68cfa8a. Could you check is the icon visible v0.4.0, please?

[ValentinH]

Just updated and the icon is still not really visible:

I've installed kubuntu in virtualbox, but it looks better for me

Do you have any themes applied besides default kubuntu?

[ValentinH]

Nope I don't think so. It's the LTS version btw

[ewnd9]

Maybe it's some kind of cache, could you try to make a clean install?

[ValentinH]

Still the same... Maybe I need to reboot my computer but I can't correctly
