The bug

In 2.2.176x, new animations were added for when the logos for Minecraft: Java Edition and Minecraft Dungeons are shown.

Previously, a user could expect to see the following:
 
 

However, now, as the animation is not smooth, and seems to stutter as the launcher loads in the resources it needs to present to the user. This is what I see very often when I open the launcher:
 
 

If there was choppiness in the previous fade, it was not noticeable. The choppiness in the current animation is very obvious.

How to reproduce

1. Open the Minecraft Launcher in 2.2.143x (tested in 2.2.1432)
   The animation for the logo is smooth
2. Open the Minecraft Launcher in 2.2.176x (tested in 2.2.1769)
   The animation for the logo is not smooth
