If I run my app on Mac, Retina, then copying TBitmap to panel (atsynedit is panel), gives not ok result. Bitmap has usual dpi. Panel canvas has retina dpi. Bitmap paints not in hi res, not sharp. TextOut on panel canvas==> text sharp TextOut on bitmap + copy to panel canvas==> not sharp What to do here? may I change bitmap? make it hi res. -- Regards, Alex
