Description

The blending mode seems to be applied to the single symbol levels of my vector layer which messes up everything. It's imho impossible to use symbols with multiple layers if the blending stays this way.

I'm attaching a project which shows the problematic behavior as well as a screenshot.

should not a new feature that does not work as expected be tagged as blocker? Cheers!

Anita - can you let me know what if you have render caching enabled or disabled?

I get correctly looking results if and only if render caching is enabled.

#5 Updated by Nyall Dawson over 6 years ago

Ok. I can see what's happening here -- I'll start work on this now.

Anita - can you please test with

https://github.com/nyalldawson/Quantum-GIS/commit/b10cabfa63f0a9ebdfeb92d168e2c159a7b26639

and let me know the results. In particular, I'd appreciate testing with the map in composer and exporting the composer to images.

I'm pretty sure this change should fix the issue, but extra testing would be nice!

Still broken in current nightly QGIS code revision 1570240. Will test again tomorrow.

Sorry Anita - I hadn't pushed that change to master yet. I've done that now (I'm confident this fixes the issue). We'll handle any other issues that popup in separate bug reports.
