(4.13.0) UMG auto-tangents wrong on keyframe insertion
I'm assuming this is a bug in 4.13, but when you add keyframes to make a border widget fly in and out, extra "animation" occurs, even between 2 keyframes of the exact same value. This is due to the auto-tangents not interpolating correctly. The workaround for now is to click the "Show the animation keys in a curve editor" button and make sure in the left-hand timeline window that your border widget (or whatever you're animating) is selected. This will show you the keys and the curves between them. Then box-select your keyframes and click the "Flatten" button (or right-click on one and select "Flatten") to flatten each tangent.
Thank you for your detailed reproduction steps. After running through them, it appears that this is working as intended. Sequencer tries to smooth out animation by default. I hope that this information helps.
Make it a great day
