Hello,

I have a problem with OBS Studio 0.15.x and scene on the source. I have a scene named Scene 1 that contain an picture with opacity at 50%. When I add this scene on the source of Scene 2, the opacity is not the same, I have not add opacity on the scene source. The opacity is 25%, 50% of 50%. I have the same problem with text, video or game capture.

Bellow, the procedure for recreate the problem :

1) On the scene 1, add a picture source, on the picture file, add a white picture.

4) Switch beween 2 scenes and see that the opacity of the picture is not the same, on scene 1, the opacity is 50% but on the scene 2, the opactity is 25%. You can add beside of the scene the same picture with opacity to 25% for comparaison.

I'm still having this problem on 19.0.3. I can work around it by doing some math to get the opacity I want, but it's a drag.

Recent bug report: https://obsproject.com/mantis/view.php?id=1108

Related report erroneously was closed: https://obsproject.com/mantis/view.php?id=851

by @Xaymar were resolved some opacity bugs with filtering (https://obsproject.com/mantis/view.php?id=954) and by @Jim (https://obsproject.com/mantis/view.php?id=699), at least ALT+drag cannot multiply the opacity drop caused by scene cloning, but this one (cloned scene) still takes place.

Also, the opacity change becomes visible as soon as you have any filter that applies to this Scene and you have to switch it on/off via eye icon (even with empty Crop/Pad filter)

I think, this is long term issue, so I attached .mp4 file with short example (zip archive)
