After the arrival of 3.19 (congratulations!) Hans tested the 
gb.poppler-version as modified by you and he came to the same result as I:

The text rendering of the gb.poppler-version cannot compete with 
gb.pdf-version!

Actually you only increased the resolution of the PDFDocument in the 
gb.poppler version to 150dpi but it doesn't reach the quality of the 
deprecated gb.pdf version in a DocumentView - even at default 
resolution. The result of the gb.poppler-version even worsens at higher 
resolutions like 300dpi.

If you compare both versions (you must look carefully) you will 
certainly see the difference too. Here a screenshot:

- Upper = gb.pdf-version @ default resolution

- Lower = gb.poppler-version @ 150dpi
