[UE5.0] Using the "browse to asset in content browser" button in BP , causes extra GPU memory usage.

Using the “browse to asset in content browser” button in BP , causes additional usage of a lot of GPU memory.
For example , I have a static mesh in a folder with other meshes .
And a BP_character with this static mesh component.
If I check this folder in content browser with tiles preview directly , just occupied about 10% on my 8G GPU memory.
But if I click that “browse to asset in content browser” button in BP of this mesh component for checking preview meshes in content browser , It will cause extra 40% GPU memory and don’t know how to release.

It is hard for my poor 8G graphics card.

4.27 dosn’t have this problem.
Any one has this issue?
