Hey,

I have a problem with playing and mixing animations using Unity Timelines.
I was looking into this problem for quite some time, but I cannot figure out what is going on.

I created a video that clearly shows a problem I'm experiencing. It was recorded without closing Unity in the meantime.
I start with idle animation and then play the second animation. You can look at one arm of our characters - sometimes the white cloth is appearing.

I performed 8 tests:
TEST 1 - the animation is played from code using SetAnimation() - ok!
TEST 2 - the animation is played from code using SetAnimation() - ok! (never seen any problems using SetAnimation())
TEST 3 - the animation is played using Unity Timelines - the white cloth is appearing - not ok!
TEST 4 - the animation is played using Unity Timelines - the white cloth is appearing - not ok!

ADDING A LINE OF CODE AND REFRESH

TEST 5 - the animation is played using Unity Timelines - the white cloth is not appearing - ok!
TEST 6 - the animation is played using Unity Timelines - the white cloth is not appearing - ok!
TEST 7 - the animation is played using Unity Timelines - the white cloth is appearing - not ok!
TEST 8 - the animation is played using Unity Timelines - the white cloth is appearing - not ok!

I cannot reproduce this. All I know is that after refreshing assembly for some time it is working ok, but for other people using Unity (e.g. animators), it seems totally random.
I was looking into the Spine Unity Timelines code, but I cannot see any big differences between playing animation from Unity Timelines and from SetAnimation().
This is killing me... :tear:
I'm debugging it for quite some time but without any progress.

Do you know where I should look for the solutions?

Thank you!
