This seems a regression of Qt5 compared to Qt4. It looks like pixel buffer support has been completely dropped (even for the deprecated QtOpenGL module and internally FBO is used). So, either add the key "DisablePBuffers" or "CoinOffscreenRenderer" and set it to true (under BaseApp/Preferences/Document). With the real pixel buffer under Qt4 we had the best results because anti-aliasing was supported and transparencies worked quite well, too. Now with Qt5 we can use FBO which also supports anti-aliasing but totally fails for transparencies or use the old built-in Coin offscreen renderer that supports transparencies but no anti-aliasing. |
