mate panel 100% CPU

[sercik]

Thank you for this nice distribution. fast, responsive and low ram usage  ;)
I have this problem: mate panel uses 100% cpu and freeze my system for some seconds when i open the menu.
It happens with menu bar (default in sparky) and also with main menu.
I also rebuild from source mate-panel and libmate-panel but the problem in unsolved. For the rest the system seems perfect.
And i also installed openbox and usu it with pcmanfm e lxpanel as an alternative to mate and is ultrafast and light.
BYE! :D
