Lag spike when triggering a transition for the first time

Hey :slight_smile:,

I’m building a UI and when I trigger a USS-transition for the first time I get a massive lag-spike for a frame.
Usage Hints are set to “Everything” for all elements.

My minimal setup for reproduction looks like this:

The USS:

.linkUI{
    transition-property: top;
    transition-duration: 1s;
    top: 0;
}

The LinkUI has a bound property which simply changes the top Style property like:

style.top = value ? 100 :  0;

The moment I trigger the change, I get a lag spike for around 100ms, after which repeated changes do not cause any lags. According to the docs, a lag spike is expected if moving an element without usage hints, but those are set. Not really sure what else to try.

Any help would be appreaciated.

After restarting the Editor today, the issue seems to have resolved itself.
