Asynchronous window sliding

[Morgerion]

Thanks to the upgraded monarch, I was able to make sliding windows.

But the following problem has come to light - the windows slide unevenly.
You can see it in the video if you look closely.
This can also be seen in the screenshots:

Apparently, for some windows, the transition is triggered a couple of frames later.
This could be remedied by passing some sort of start time to all transitions, and compensating the delay via a negative delay in the gui.animation().

This effect is very noticeable on the mobile:

I was able to get rid of the background shift when sliding. I had to do some trickery with skipping frames before animation, but now it's stable. :)
However, when it comes to the GUI specifically, it still lags:

The fact is that the middle window consists of two entities - the 3D scene and the GUI itself. I slide the 3D scene into the background on its own, and there is no problem here. But there is still a delay with the GUI sliding, and it is clearly within Monarch.

I'm not sure if/how to solve this with the current design in Monarch. I can take one final look if you can prepare a minimal project where this problem can be seen. The other solution is to not use Monarch for the problematic screens or for those kinds of transitions.

here's the project:
__test_slide_GUI.zip

and here's a video (from this project) that shows where the lag in synchronization is noticeable:

Let's say we always have two windows when sliding:

• IN_Window (the window we arrive at)
• OUT_Window (the window we're leaving from)
  For some reason i don't understand, IN_Window starts its animation 1 frame earlier than OUT_Window.

This problem can be solved without using the standard transitions from monarch. But even in this case you will have to manage the delay of 1 frame on PC and 2 frames on mobile devices (i don't know why this happens).
