There is no other way. We opted not to use the standard Windows controls or the standard Delphi controls in our application and implement our own set. When painting, we add every area we paint actual pixels to an overarching tracking Region and then only erase the non-painted pixels by subtracting said Region from the Paint Rect. Smooth and flicker free and as an unanticipated side benefit, it's very TS friendly. We had clients comment on how little bandwidth our application needed whilst offering nice interactive feel under TS back in the pre-jetstream days. Yep – that’s very true. There is no other way.
