Description askkegra 2023-08-24 14:21:19 UTC

    I love the new Blending Info for layers in the layer docker. Is it a known issue that the %-value for opacity is slow to update between the slider and the blending info?

    When I change the opacity of a layer the blending info take a hot minute to update. But if I click on the layers list or outside the main window it updates immediately.

-

For me it never updates, unless I

    click in the layer list (any interaction there)
    hover over active layer
    make a stroke - updates roughly 1.5 sec after, i.e. at the same time as preview docker

Undo/redo updates it too, but only if the stroke is included in the sequence. Any other interaction with the UI does not trigger the update as far as I can tell.

Make sure that the node emits nodeChanged() signal on opacity change

That makes the layers model to update the item in the list
