For example this is what my current report looks like in report viewer and exported PDF respectively:
As you can see there is an additional spacing created between lines. I'm pretty sure this problem didn't occur until updating to the newer version of the report server. I've done a bit of testing and one thing I've noticed is that this for text values that include Line Feed i.e. CHR(10) will look like the above but if I change to only using Carriage Returns i.e. CHR(13) it will instead work properly in PDF but not in the report viewer as below:
I would appreciate any help to get the export back to being consistent with the report display.
