When using the "Volume by Price" study configured for Multiple Profiles, enabling the "Use Transparent Draw Style" option causes significant lag / poor chart performance (slow scrolling, redrawing, zooming). Disabling "Use Transparent Draw Style" restores normal performance. The issue scales with the number of profiles displayed. Could the transparent draw style be optimized, or is this expected behavior with the current rendering approach? Sierra Chart Version: 2897 64-bit
