Nowadays a lot of rendering goes through 3d engine - as long as one has 
capability, why not ? And it makes it easier to work with images, alpha, 
etc.

Thus just because a program is 2d does not mean it does not use the 3d 
graphics.

For example, one of the simplest way to make a movie player that is 
capable of displaying multiple streams is to use opengl to paint frames on 
2d faces. It could make a rotating cube, of course, but that is hard to 
watch :)

Look in settings - this depends on whether you use KDE or unity or 
something else.

The compositor is used for desktop effects like window zoom or making your 
windows partially transparent.

Another suggestion is to try upgrading to 20.04.
