Hello. I found strange thing.

I have a project where lines width is calculated with such expression:
"width_coefficient" + to_real( @TEST_VAR_WIDTH )
where "width_coefficient" is column and @TEST_VAR_WIDTH global variable in qgis.

Here how layer looks like when @TEST_VAR_WIDTH = 0

And now @TEST_VAR_WIDTH = -0.5

Everything works fine but when I try to print as pdf from composer I get all lines.
See export_pdf.pdf

I've created test qgis project with one layer and composer. You can try it yourself.

QGIS version 2.14.17-Essen
Compiled against Qt 4.8.5
Compiled against GDAL/OGR 2.2.1
Compiled against GEOS 3.5.0-CAPI-1.9.0
