I'm having real problems with the map window display of translucent rasters (when in both map window and Layout window). I have a polygon layer with solid colour underneath Ordnance Survey raster layers, but in v17.0.4 the polygon colour is showing solid on top of the translucent raster. With OS 25K, most of the solid polygon appears above the raster. With OS VectorMap Local it seems to be mainly features like roads. The tiles are TIFS, displayed with a seamless table.
This doesn't happen in v15.0, which I still have. I have tried comparing all the settings and making them identical, but it makes no difference. I have tried with Enhanced Rendering enabled and disabled backstage and under Map>Options, and with different smooth settings. I am having to revert to v15 for this kind of mapping as I can't make it work in v17.0.4.
I attach some examples to show what is happening - the v15 image shows how I want it to look.
If anyone else has had this problem and overcome it, I'd be very grateful for any tips.
Many thanks,
Jane
