I have a decently high end system and yet this application runs horrible on my hardware. I have tried different methods of installation: portable, jar standalone and the normal install, but the problem persists. I have also tried java version 8,11,17 without change.

It seems to have something to do with the 3d view, since moving anything else doesnt affect the performance. Here is a video to show how bad it runs: https://youtu.be/X0Xb21k6lLk

Could this be a problem of running under the Wayland display server and thus under XWayland since it is Java. I could not find any meaningful logs unfortunately

I had the same issue with Sway on recent Intel hardware. 3d acceleration is perfectly smooth using the online version of SweetHome3d in Chrome and Firefox, but the desktop version is rendering at 1 fps or less.

I found a fix. The 3D view is now perfectly smooth if I start the desktop app with this ENV variable:
```
JAVA_TOOL_OPTIONS="-Dcom.eteks.sweethome3d.j3d.useOffScreen3DView=true"
```
