It was difficult, but I found the problem - this is a bug in Unity UI.

This is a bit hard to explain, but I will try:
When you rotate Image along the X axis, all points on the Y axis have different distances from the camera.
When the distance to the camera is greater than the distance to Canvas + some value, some Unity APIs (for example, RectTransformUtility.ScreenPointToLocalPointInRectangle) stop working correctly.
Most likely this method makes raycast with a distance limit that is less than the bottom of the map.

I fixed the jumps when entering this area.
Updated script attached.

But there is another problem:
This area will ignore any interaction due to the bug above.
To work around this, increase the Z position for Image GameObject.

Thank you for the video.
I was able to reproduce this bug.
I don’t know what is the point of rotating UI element along X axis, but this is definitely a bug, and we will fix it.
I think the fix will take 1-3 days.

P.S. I removed the link to your video, because it contains your invoice number.

Sorry, maybe I didn't make it clear, now I attached video for you
For my implementation, I needed my UI to be tilted 30 degrees. And than I noticed that the map got stuck when dragging it. I don't now if it's some bug or it's normal state of working with UI components in Unity, but I glad that now it working. Thank you for help!

Honestly, I do not know how to comment on this.
I tested more, and did not see this problem at all in the latest version of the asset.
If you have ideas on how to reproduce the problem, I will try to do it.

Thanks, now it working better.
But I still have one problem with map stucking while drag. Sometimes when you drag map it got stucking for no reason

No, it does not require any special configuration.
Here is a video about creating a UI Image map in an empty scene:

I update version to v3.6.4.1 and nothing change. Maybe exist some special way to setup UI controler?

Hello.

What version of Online Maps are you using?
This bug has been fixed in Online Maps v3.6.3 (available through the built-in update system).
I checked on the latest version of the asset, and this bug does not occur.
So just update Online Maps through the built-in update system.

Map dragging problem

I have problem with dragging online map while using UI components for displaying map (video attached)
I tried to display map as Raw Image and Image components but none of them worked correctly. (in each case I use proper control component)
I tried to off "Render in thread" and set size of UI elements to N * 256, that didn`t help me. Maybe you can help and explain correct settings for rendering map on UI elements?
Also I tried display it with sprite renderer and in this case it works fine
