I just bought a new Windows 10 laptop, and I'm regretting it already.  I
installed openSUSE 15.3 dual boot, and the problems are unending.  POV-
Ray renders normally, but the display window does not show for versions
3.7 or 3.8.  The display window does appear for versions 3.5 and 3.6.

Asking for advice on non-POV-related matters, I was suggested the
following command; perhaps the output may be relevant.

Supposing you compiled yourself, my guess is you have no 'compatible' 
Simple Directmedia Layer development library installed. POV-Ray will 
compile cleanly without a preview window capability.

The official v3.7 and v3.8 versions use the much older SDL1.2 libraries 
and not the current SDL2.0 ones.

As a quick check for SDL1.2 issue the command:

sdl-config --version

(The command is 'sdl2-config --version' for SDL2.0+)

Neither version was installed on my computer.  I installed version
1.2.15, and still no preview.  Do I have to recompile POV-Ray?
