Graphics screen messed up after a minute

[ErikJan]

New to SH3D. Installed but after a minute or so, my screen gets messed up (graphic elements refresh in the wrong place). I have no error messages and in the very short time before the graphics problems start, all works fine.
I tried 32 bit, 64 bit, JavaStart... nothing helps.
I use an up to date Windows10Pro 64bit system (Intel i7) with an up to date NVidia 970; I have 8 Gb RAM and plenty of disc space.
I think I like the program very much from what I see, but I can't use it. Anyone with suggestions as to what I should do?

Please try the suggestion I posted here:
Download Sweet Home 3D 6.0 installer, run the installer (or run it again if you already downloaded and installed that version) and select the option 32 bit when prompted.
Once installed, download the file SweetHome3D.l4j.ini and copy it in Sweet Home 3D installation folder to run the program with DirectX rather than OpenGL

I did that but that does not solve my problem.

Note that I have the same problem as here it seems: https://sourceforge.net/p/sweethome3d/bugs/833/

Sorry, but I have no other idea.

Thanks. Such a pity... I would really like to work with this program. Seems unique in its kind. I just tried the portable version (5.7): same problems. I can try 32 bit, 64 bit, normal, protable, JAVAstart or anything... Within 5-60 seconds my graphics are messed up. My system is never giving me problems with anything.

Give it a try with a Linux live system (Ubuntu for example).
