MeterSlider::paintEvent() does not update the left-most pixel column when user adjusts volume while playing
If I lower the volume slider value while playing back music, I can notice a glitch in the rendering:
If you look at the leftmost pixel column of the meter, you can see that it still has left behind the previous filled color image...i.e. it hasn't updated that part of the rectangle.
Similarly, if I increase the slider value while playing back music, you can see it leaves behind the previous "unfilled" color that left most pixel column:
This is a very minor visual glitch, but nonetheless I think important to fix for professional presentability purpose.
Present in 2.0.3 as well as latest 2.1-dev and 3.0-master.
