Description
In current master (as of 03916d5 - Sep. 3) there is something seriously broken in data-defined symbology.
Actually I don't know if it is the data-defined symbology or something bad on the provider. Anyway, please have a look at the attached project. In this project I use data-defined coloring and data-defined stroke-width.
If you navigate or reload, you can see that colors and line-widths randomly change - as if there suddenly would be different attributes attached to the same geometries.
Something is seriously broken.
I know that bcaee65 from 15 days ago was still ok.
I am trying to narrow down the issue with different commits.
