Drawn Chart Objects Flickering When Chart Scrolled Since Build 2485 Update

[Robert Northen]

Hello

I have an indicator that draws several rectangle objects across the chart as part of support/resistance lines. These objects are drawn in the OnChartEvent when id = CHARTEVENT_CHART_CHANGE. The indicator has been recompiled for the latest MetaTrader build - 2485.

Before the update there was no flicker, but since the update there is now a very noticeable flicker when the chart is scrolled left or right using the mouse. Scrolling a bar at a time using F12/Shift F12 does not produce a flicker.

Any ideas?
