Any news here? I have the same issue but with a regular display, Ubuntu 18.04 and the Sweet Home 3D snap version (current 6.1.2). I tested it on two laptops with different screen resolution (full HD and lower) and different graphic cards both with the same result. Under Windows (on the same computer) Sweet Home 3D is working absolutely smooth. The option -Dsun.java2d.opengl=true improves the situation a bit but creates some graphic display issues.
Hi all, Dorin, thanks for the nice symbols! While using it I discoverd that the symbold are to large (5m x 5m). I changed the script to set the size to 25 cm x 25 cm and created a new library. The results can be found here: Library: https://github.com/AlbrechtL/Symbols-electrical-de/releases/tag/v1.5.6 Sources; https://github.com/AlbrechtL/Symbols-electrical-de
