I am affraid that is problem. For HW acceleration cannot be different surface. When I first designed code that no good works.

You can drag the view with mouse button pressed.
Mouse lags in that demo for some reason, i believe it's one other DelphiX bug. Lag stops if i limit interval.

There should be showing a rotating Add blended texture, but for now it shows only if i take hw acceleration off, only lagging as hell

Edit: OH! One suggestion: Could you make there a bi-linear texture toggle in DXImageList items? I noted bi-linear textures are used in StretchDraw only. It could be expanded to rotate and other functions too.
