Placing the cursor at various points in a document causes the VA Outline window to flicker every time it updates, even when the only visual change is that one entry becomes bold and another is no longer bold.
Any chance that window could get some double-buffering? Or something equivalent to that?
If you right click inside VA Outline do you have "Auto Expand Nodes" turned On or Off?
So far, checking on two different machines here, I am not seeing anything I would call a flicker. There is a slight "something" where the bold item is being moved, but if I focus on other parts of VA Outline then I am not seeing any sign of a flicker or redraw. I am testing with Auto Expand turned Off and VA syntax colouring in VA Outline turned On.
