Hello and thank you for the support,

I'm showing below the prints of the problem.

Other info which might be helpful:
I'm using the version Sweet Home 6.3 / Java 1.8.0_202 32bit
and I have extra installed for Furniture and Textures editor purposes:
-Java Version 8 update 281 (build 1.8.0_281-b09)

(the built-in java in the Program didn't work for me)

I believe the extra Java version 8 is not the problem because
I did a rollback in the Windows 7 restore points to before
the Java installation and the problem remained.

Usually shows this:

After a few restarts of Sweet Home and sometimes
the computer, shows the correct image, like this:
