Eyedropper bug?

[Lucky Clan]

I have been trying to reproduce that for few hours, but everything looks ok...

Could you record one more video with "Visualize Touches" enabled?

One more question - do you paint with Apple Pencil and sample color with finger?

[athebyne]

No, I only sample with apple pencil. I will make a video, but it will take me some time.

This is probably the easiest way to trigger it (for me at least):
1. setting the sampling mode to "current and below" (changing the sampling often fixes the bug, but it also occurs spontaneously during work)
2. restart the application
3. create a new document, a colored background layer (1) and a few strokes above on a new transparent layer (2)
4. create a new layer on top (3) and make a few strokes on it. Sometimes a 4th layer is needed. Eyedropper should catch colors from the layers below but not from the one you are currently drawing on.

I'm doing exactly the same steps...
Do you use version 4.0.5?

[athebyne]

I believe so, I don't have any updates available. Here is the video, don't want to compress it so I uploaded it to google drive: https://drive.google.com/file/d/105yX2Nd18w-o3MGDVYYmwY9lg_Ab8bis/view

You can tap Artstudio > About to check the version.
How about ipadOS - is it ipadOS 15.3?

[athebyne]

Yes, it's version 4.0.5, and iPadOS 15.3.1

One last question - which iPad model do you use?

[athebyne]

iPad Pro 12,9" (2020) 128GB Wi-Fi

[Lucky Clan]

I still cannot reproduce that.
Few idea/questions:
1. Do you rest your palm on screen when painting / sampling?
2. Can you close app, remove it from background and try again?

[athebyne]

1) Yes, but I just checked and found that in both cases the wrong color is selected.
2) After restarting and auto-loading the file, the layer I was drawing on has updated colors and samples correctly BUT my next brush strokes are still no longer registered.

[Lucky Clan]

After many hours i reproduced that once, but after launching app again it is working fine...

[Lucky Clan]

Can you record one more video, but first close app, remove it from background, then start recording.

Could you show me a panel with Bucket Fill settings?

Does it also happen when you don't use Bucket Fill tool?

[athebyne]

I tried it without the bucket fill and it broke down too. I just found out some bizzare things here... I recorded two videos.
