Description Frank Steinmetzger 2022-03-06 01:38:51 UTC

SUMMARY
When I want to delete several clipboard items in succession, it is not possible to just repeatedly click at the place of the delete button and let the items move up under the mouse cursor, because the button of the next item does not appear, even though it would be right under the mouse cursor. If I now click, the item is instead selected and the popup closes.

In case my description is not good enough, I’m happy to provide a video capture.

STEPS TO REPRODUCE
1. Have several items in the clipboard.
2. Move mouse over the delete button of an item and click it.
3. The item is deleted and the items around it move up to fill the space.
4. Click again where the delete button was to delete the next item.

OBSERVED RESULT
The delete button of the item that moved up does not appear unless the mouse is moved again. As a result, the click does not trigger a delete action, but instead selects the item and the clipboard popup closes.

EXPECTED RESULT
I would like for the buttons to appear, because they are right under the mouse cursor in that moment. This is quite the same behaviour as when I delete items from the notification list (where the dismiss button is not hover-activated) or from the (vertical) tab bar in a browser.

That's exactly what it does for me, and what it's supposed to do.

Can you attach a screen recording that shows exactly what it's doing for you?

First I delete item “a”, then click on where the delete button would be for item “b”. But instead of deleting, I select it.
Then I open the panel again (note that “b” is the topmost one item) and delete it and item “c”, including moving the mouse afterwards, so the delete button reappears. Then I delete item “d” and don’t move the mouse, which prevents the delete button from appearing. Thus I select item “e” with the next click.

Thanks, I can see what you mean.

Unfortunately (or fortunately?) it works as expected for me. There have been a number of focus-related changes to the Clipboard widget in git master since 5.24 was released, and I think it is likely that one of those changes fixed it.
