Description pbs3141 2021-05-07 16:21:14 UTC 
SUMMARY

Freehand lines can be made to appear at the top of the next page, or the bottom of the previous page, if that page is clicked before drawing the line.

STEPS TO REPRODUCE

1. Open a PDF document with more than one page.
2. Select the 'Freehand Line' tool.
3. Click on page 1 without moving the mouse by even a pixel.
4. Draw the annotation on page 2.

OBSERVED RESULT

The line appears on page 1, crushed into the bottom of the page making it nearly invisible.

EXPECTED RESULT

The line should appear on page 2.

I don't understand how you can draw an annotation in page 2 without moving the mouse that is on page 1, can you clarify?
Comment 2 pbs3141 2021-05-07 22:09:31 UTC 
In step 3, you should just click and release, taking care not to move the mouse in between.

The only reason I emphasized this was because it's quite easy to do accidentally, but it makes the bug disappear.

Ah, i see what you mean, doing a single click on one page starts the Freehand Line annotation but doesn't finish it so you can go to another page and pretend to do the annotation and it doesn't work because it's still happening on the first page.

while you're here you would prefer that a 1 click annotation creates a mini annotation of just 1 point or "does nothing"?

I'd never thought about that. I suppose as long as the result would be visible, it makes more sense to create a mini annotation.
