So you're not using a HiDPI screen, and I don't experience your issue with Sweet Home 3D Russian on my side, so it must comes from something else.
Wouldn't you use a [font=courier new]SweetHome3D.l4j.ini[/font] file a resolution scale line like
Code: Select all
-Dcom.eteks.sweethome3d.resolutionScale=...
Or maybe you changed user interface size in Windows?
Could you also install Sweet Home 3D 32 bit to check if it renders differently?
