    Are you serious? Unity 2018.3 has been released in December 2018, so we have to wait december 2019 to get this fixed? Really ???

    Come on Unity, this is basic functionality! We cannot work for ~6 months for a fix for something so common.

    Fixed in Unity 2019.3 ?? I mean, this is a quite common use case right? Unity 2019.2 is still in beta and this is fixed in 2019.3? That is another a few months right? Why are you doing this, Unity? Why?

    I assume that changing sprites via scripts is common, which makes me wonder why this issue does not get prioritized. We swap sprites with code in every place in out game and it just causes malformed images. This is the one reason we did not migrate to Unity 2019 yet.

    i had that issue on 2 groups of things in 2019.1.0f2, after update to 2019.1.1f1 one of the groups started to work as supposed (all the alpha tweening is displaying correctly), but the other usage where i tween alpha to 0, then change the sprite and tween back to 1 isn't working like before (if I change it from simple to let's say filled it displays but not with simple)

    so i was looking and i found 2 differencies - the not displaying sprite was rect mesh and not in atlas ... so i checked mesh and still no success but when i atlased the sprite it started to display

    i guess the bug was half fixed in update to 2019.1.1f1 but since it works only with atlased sprites (the particular image isn't POT)

    Hack to fix: replace from "Image.sprite = Sprite;" to "Image.overrideSprite = Sprite;".

    ETA for a fix? This is a breaking issue for me and it is holding up from releasing updates. Currently on 2019.1.0f2

    This needs to be not disabled for voting since it has not been fixed yet. I'm trying to vote for this issue to be fixed
