Icons bug

Hello,

I made an update of my Observium following these two commands : 

cd /opt/observium
sudo svn update

My Observium is now updated. However, as you can see in the attached screenshots, there is those little bugs on the icons. 22.8.12241 (stable) (observium-new-icon-bug.png).

There is no problem with another version of Observium which is older 21.10.11678 (stable) (observium-old-no-problem.png)  

Could you please investigate?

Tell me if you need more informations.

Thank you
