I submitted a bug report on this already, but I wanted to bring it to people's attention in case they're having trouble upgrading their project to 2019.1 Bug 1148001: https://fogbugz.unity3d.com/default.asp?1148001_nqqefj6nd7mfm5aq It has been talked about in the archived beta forum, but it is still present in the released 2019.1.0f2. https://forum.unity.com/threads/sin...-canvas-are-all-colorless-dynamically.661456/ Observe in the screenshot how the selected Image shows up as green, even though in the inspector its color is purple. Calling Image.DisableSpriteOptimizations after setting the image causes the color to start updating again. But, I don't know if this makes the image generally less efficient than in 2018.3. I'm attaching a small sample project that demonstrates the issue (which was also included in the bug report).
