It may look nicer without flashes, but since we destroy the entire UI and rebuild it, the flashes are unavoidable.
The transition between simple and advanced could be made this way but nto the one to and from vintage.
Since the expected usage is to set the view mode and stick to it, i think my time is better spent on actual problems that break things.

since we destroy the entire UI and rebuild it, the flashes are unavoidable.

I do not think that is the problem because it only occurs when the UI is in a maximized state, not in windowed mode, regardless of how large the UI is, and the UI is presumably destroyed and rebuilt in both cases. I resized each side of the UI to 1 pixel from each edge of each side of the screen, and the flashes were not present. That is as close to a maximized state as one can get. The problem seems to be that the UI returns to a maximized state after rebuilding it. I wonder if it may be related to this, though I have not seen that problem since the most recent Sandboxie Plus versions.

Using 1.2.6 there are sometimes white flashes, but not as bright compared to how the other issue shows, when going from minimized to maximized. Not pretty, but no great concern. Arguably there are more important things to be fixed, but keeping it in mind when touching the UI, might be a good idea.
