Refine selection tool severely lagging/disappearing in iPad version

[RosaL]

As you can see from the video below something is up with my refine brush tool (and also the selection tool) and I can’t see it as I use it making it very difficult to see what I’m doing. Any idea what’s going on?

Hi @RosaL,

Welcome to the Affinity Forums

I'd like to try force restarting your iPad, as this will clear the apps cache and can fix oddities on the iPad. Please find our FAQ below for steps to perform this -

Once restarted, launch Photo and try refining your selection once again. Does this reduce the lag you're seeing please?

Hi @Dan C

thanks for the welcome. I’ve tried the reboot and unfortunately the same thing appears to be happening. Any other suggestions?

The performance depends on certain factors, e.g.:

• document size in pixel (ok to about 24 MP, degrading for larger files)
• Not having RGB/8 color format, especially LAB degrades severely
• heavy filters like blur / sharpen with huge radius (100 or 100px)

Any chance you can upload the document so we can check on our devices?

Which iPad model do you have?

@NotMyFault thanks for the reply! 
 

I'm a complete newb to photo manipulation etc so I don’t quite understand all the terminology 🙈

I’ve taken a screenshot of the document when I go to export, does that answer some of the above? There’s no filter or adjustments on it, I was just trying to cut the flowers from the background but this seems to be an issue for with with other photos too, regardless of the size of the document. 
 

in terms of iPad I have a 7th generation, model number MW752B/A.

what format is best for the document upload?

[NotMyFault]

Your iPad seems fine, newer and more performant than my own.

Please check if you have the latest OS version, there were some nasty issues with older.

The file sizes seams reasonable, too, so normally you shouldn’t see these delay issues.

For upload you could simply choose the original afphoto format.

Thanks for trying that for me and I'm sorry to hear this - in your screen recording the brush size when refining is 4.7px in size, which may explain why you are unable to see the refine brush strokes.

If you increase the size of the brush here, are you able to more clearly see the selection you are making?
