Mixer redraws twice? (when resizing)

There is a mixer redraw glitch which is visible for a split second. When I resize the mixer, there seems to be an intermediate (and wrong) draw state, followed by one more final redraw to the correct size. For example, when I resize the height from default to very high, I see the mixer tracks first draw all the way up, then redraw back down to make room for the FX slots.

bump...... glitchy redraw still there in 3.03

still there in 3.161 most obvious when mixer is docked on the bottom (default installation)

I can sort of see it, do you mean the flicker it does?

Confirmed here (3.162pre2)! Another one: + On Undo/Redo of volume fader changes you also get flickering of the mixer:
