Title: Avoid useless lag when comboBox are activated without changing the index

When we change the value either on filterCombo or modeSelector, there is a little lag due to the processing of the change.
This lag is also present when we select the filter/mode currently enabled.
The aim of the request is to fix this unwanted lag.
