Apple Pencil notes often lose strokes after save

[spinality]

I noticed an annoying behavior change several months ago. Not sure if it’s related to an iPadOS update, or something in igigbook. I first enter a series of normal annotations, which look correct on screen. Then, after hitting the save icon, many of the small strokes vanish such as crossbars on E or F, dots on I, strokes on sharp symbols. I imagine it has to do with iPadOS removing unintended noise, such as hand touch artifacts. This problem was not present before; I use annotation extensively. I was very aware when it first started. I use a recent Apple-brand pencil on an iPad Pro. Again, it’s not that the pencil isn’t being recorded. The strokes are all there, until I hit the save icon. The problem may be more common on the top 20% of the page. (I sometimes think this is the case, but then other times it doesn’t seem to be.)

My fear is that it’s some Apple change, but I haven’t seen similar behavior in other contexts. Has anybody else experienced this? Any suggestions for how to reduce the frequency? I haven’t found any pencil settings or other helpful mechanisms that might be affecting it, but it’s easier to miss features in the accessibility pages.

Do you have before and after images?

Do you have before and after images?

I will start trying to collect these. It’s challenging because by the time I observe the “after” it’s too late to get the “before.” I’ll need to start grabbing a screenshot before each save. I thought I’d first ask if this were something you already knew about.

I’ll follow up with an example when I can capture it.

Here is an example. The initial edit:

After save, where a few E, F, and A crossbars vanish on the top line. In this case the lower line was unaffected but that varies.

Can you send us the ".idraw" file via email?

I didn’t save it. I will try to recreate an example and send the images plus .idraw file.

Thanks for those files. I see the before and after images, however this is not something we can reproduce here using any version of iOS.

As I feared. It could be some combination of Apple software updates and the particular Apple hardware in use. I’m guessing it might be involved with the cleanup of hand-touch artifacts. Thanks for looking.

If I find any other clues I’ll pass them along.
