What to do?

In this particular case, symbols/amenity/bureau_de_change.svg is the problem. But there are more icons that have non-supported elements.

Apparently this does not damage the rendering. Should it be fixed anyway?

[matkoniecz]

Is element logged as problematic having any effect on rendered image? If that it NOP then it certainly should be removed to reduce spam in logs.

I'm not getting these. What is your rendering setup, in particular, what version of Mapnik?

In any case, regardless of why I'm not seeing the issue, symbols/amenity/bureau_de_change.svg clearly doesn't meet our map icon guidelines

ref. #3301

[sommerluk]

Only when using single-tile rendering with phyton. Does not occure when using kosmtik.

So the issue is that the code of symbols/amenity/bureau_de_change.svg needs to be cleaned up?

There was a mention of other icons, all of which would need cleanup to meet our requirements.
