How to fix this problem

I tried to set fixed font using dconf in
org.mate.peripherals-keyboard-xkb.indicator.font-family=Ubuntu Regular 12
but always getting blurry fonts

I played with different settings and I found one solution to this problem is to set panel height to 30pixels to get Keyboard indicator to display correctly the current keyboard letters. Now it is displayed correctly but with some huge panel.
