document raster effects settings not being honored on all affected objects

Thanks all of you! 

I reported the issue over on 

https://illustrator.uservoice.com/forums/601447-illustrator-desktop-bugs/suggestions/50923838-document-raster-effects-settings-not-being-honored

@c.pfaffenbichler Can you report it to UserVoice as a bug? If so please mention the UV bug report here so more users can vote and comment.

Thank you all! 

@Anubhav M , I cannot share the files because they are a customer’s. 

@Kurt Gold , sounds just like my problem. 

The screenshots show what happens when I change the Document Raster Effects Resolution setting – part of the effects are not updated at the correct resolution, editing the effect causes an update.

(Edit: In the last screenshot the differing resolution of the top left square’s Drop Shadow should be clearly noticeable.)

There is certainly something wrong with the updating of effects when the raster effects setting is changed.

Most of the time it does not update the drop shadow, sometimes a single object is updated but others aren't.

Sometimes it updates, but the next time it does not.

It does not seem a new unreliable behaviour because it is reproducable in older versions.

Carl,

probably you detected another serious bug in (one of) the latest Illustrator versions, but I'm not quite sure if you mean the same issue as me.

Here is a simple test that explains what I mean (in Illustrator 30.1):

- In a new document open the Document Raster Effects Settings dialog and set the resolution to a low value (30 ppi).

- Draw a yellow filled circle and apply a Drop Shadow effect to that circle.

- Deselect the circle.

- Open the Document Raster Effects Settings dialog and change the resolution to a higher value (600 ppi).

In older versions of Illustrator, the new setting would be recognised and updated immediately.

Unfortunately, in Illustrator 30.1 it does not get updated automatically, that is, the resolution of the Drop Shadow effect is still set to 30 ppi (you can see and verify it by expanding the circle's appearance).

To update to the higher value, one can hide and immediately show the effect instance in the Appearance panel. Or you can slightly scale or rotate the circle.

This is a fatal bug and it may get even worse if the live effect objects are encapsulated in a symbol or an envelope.

Are you talking about the same issue, Carl? Or is it something else?

Hello @c.pfaffenbichler,

Thanks for reaching out. Would you mind sharing a link to a sample file along with a brief screen recording of your exact workflow and the problem you're experiencing, so we can better assist you?

Looking forward to hearing from you.
