Can you try upgrading to 2.4.3 or 2.4.4 that comes out later this week.

If it’s still low create a small example and I’ll ask the team to test.

Thanks for reply. I created a demo on version 2.4.3. I find it still with the above problem.

Modify the code in the engine, and then recompile the engine according to the document.
