With QGIS 2.12, I am displaying polygon outlines as dotted lines. The Print Composer screen correctly displays those outlines as dots. Here's a screenshot from the Print Composer window, showing dotted lines:
However, when I Print Composer > Export to Image (or pdf) the output file displays solid lines, not dots. Here's a screenshot from the output pdf. Note the solid lines:
The same problem happens if I select dashed lines. I'd like to have dots or dashes in my output media instead of solid lines.
Is this a bug, or am I doing something wrong?
