Issues with desktop installation- advice please

[PJG65]

I am experiencing a persistent bug where ghost/duplicate images of the screen appear whenever I click or move the mouse in SweetHome 3D. The application becomes completely unusable.
My setup:
∙ Windows 11 25H2 build 26200.8037
∙ Dual 4K monitors (32” Dell and 27” — both at 3840x2160)
∙ Nvidia graphics card
∙ SweetHome 3D version 7.5 (32-bit)
Fixes I have already tried without success:
∙ Disabled Nahimic service
∙ Disabled Nvidia GeForce Experience overlay
∙ Compatibility mode set to Windows 8
∙ DPI scaling override set to Application
∙ Created SweetHome3D.l4j.ini with various flags including -Dsun.java2d.d3d=true, -Dsun.java2d.opengl=false and -Dcom.eteks.sweethome3d.resolutionScale=2 and 3
∙ Matched scaling on both monitors to 150%
The application works perfectly on a single monitor laptop with Intel integrated graphics. Is there a known fix for this specific dual 4K Nvidia combination?
Thank you

Did you try the 64 bit version and updated to the latest graphics driver?
