Annotations may change border color, shape and features when they are moved (Ctrl + Mouse drag) within Okular. Bug can be reproduced with the document from here: https://git.pwmt.org/pwmt/zathura-pdf-mupdf/raw/f1b05ad44cf7496c6700d7476cda359efc61f027/tests/files/annotations.pdf The text annotation with content "Text box" has a red border. After moving, border color changes to black. After saving and viewing the saved document in Firefox, the annotation is not visible at all there. The text annotation with content "Callout" has a red border and a callout line. After moving, the border rectangle is enlarged, border color is black and the callout line disappears. After saving and viewing the saved document in Firefox, the annotation is not visible at all there. I can reproduce this with Okular 1.0.3 and Poppler 0.48.0, and saw it in earlier versions (which I don't remember exactly) too.
> The text annotation with content "Text box" has a red border. After moving, border color changes to black. Confirmed with git master and poppler 0.48.0 > The text annotation with content "Callout" has a red border and a callout line. > After moving, the border rectangle is enlarged, border color is black and the callout line disappears. Confirmed as well. I can reproduce this with Okular 1.0.3 and Poppler 0.48.0, and saw it in earlier versions (which I don't remember exactly) too.
Issue 1 with border changing colour appears resolved since. I can move and it stays red. Issue 2 is still present, after moving the annotation it is no longer visible in Firefox. Tested with 21.03.70 (git master).
