    I have two buttons (uGui), one is using "Transition: None" the other "Transition: Color Tint".
    Now while profiling I noticed that the button with transitions causes some spikes, both in milliseconds and memory allocated.

    I am using URP 7.3.1, Unity 2019.4.1f1 and profiled on an Android 10 device (Nokia One Plus).

    Here is a composition of screenshots to illustrate what I am curious about.

    More detailed profiler results (both with "deep profile" turned on and off).

    Does anyone have experience with this? Is this to be expected?
    Thank you
