Hi all, i was trying to set a transparent background in text areas in Draw. I replaced the call to mpGraphics->DrawRect in OutputDevice::ImplDrawText with a call to DrawTransparent on the same area. However the result has issues such as [see attached picture]: - not giving the expected color (the arrow text in the picture should be the same color as the text area's), - leaving old rendering leftovers around when text is moved (or the related arrow in this case). I tried to debug how other transparent areas are drawn but that didn't give much insight. Does anyone any experience with this or any guess on what may be going wrong? Thanks, Matteo
