Hey, apologies for the poor description of the issue. But can't seem to find the words to properly describe what I'm experiencing here.
You can see in the attached image these white angled lines, they should not be there. But for some reason they appear to parts of the canvas. To me they appear like a part of an edge of the area of the stylus that's in contact with the screen.
It only seems to mostly appear when using the charcoal type of a brush and darker colors.
This doesn't happen with with Microsoft Whiteboard.
What version of Fresco are you using? You can send me an email through Fresco's Report A Bug link (App Settings > Help > Support > Report A Bug) and all of your device/app information will automatically populate the email.
You don't have to repeat all of this, just mention that you posted here: I'd really like to get more information from you; I have only seen this issue once before.
