UIElements Animation stutter and items not showing randomly after chaging opacity 0 => 1 via anim

Unity Engine

I noticed that the animations in my editor tool are janky when they play unless I move my mouse while the animation is running. They are perfectly smooth as long as my mouse is constantly moving. If not, stutter city.

I have noticed that it is not all the time, just most of the time. I see that if I alt-tab out and then back it, it almost always ends up doing it at that point.

I retried the same code in 2020.1.5f1 and the animations are smooth all the time regardless.

I just made a repro project and submitted it via bug report, but then I noticed that one of my buttons I was animating was randomly not showing when changing Opacity from 0 => 1 via animation as well.

You can see the animation stutter : Imgur: The magic of the Internet

Hi @MostHated ,

Thanks for the reports, we’ll look into them. For future references, please create separate threads for separate topics. It would also be helpful if you could share relevant bug report IDs when you talk about bugs on the forum, that way we can find them faster.

Sure thing, my apologies.

The link I got from the bug report email can be seen here 1278085
