My general method for visualizing the data was to create a discrete singlelayer pseudocolor ramp  with two classes.  For example, if using NDWI data I would set values of [-1, 0.1] as fully transparent and [0.1, 1] as opaque shade of blue.  On Ubuntu 18.04, QGIS 3.2 I've noticed that if I only use two classes, the data isn't displayed.  If I add a third class it will be displayed.  Is this a problem and should I submit a bug report?

Could you share a sample dataset and project showing this issue?
