Why do Imagetool and Pageview flash?
As noted above, DPS allocates a small colorcube to share with other applications. Unfortunately, some applications, notably ImageTool, do not want to “play ball” and allocate their own private colormaps for each instance of the tool. This approach is not recommended, and is why these tools cause such dreadful colormap flashing. Apart from locking the colormap, there is nothing the user can do.
