Removed not needed setting of the quality to 0.

We now just hide the icon with values and show the interrupted one. Calling this one was causing troubles like flickering and stats popover not able to hide, once shown. On hover we are calling updateView which ends to this call which destroy and create the popover, which maybe is leading to this problems.
