HELP! Hiding vertices would not hide surface

[Evan_Woobin]

Hi all, I recently updated to Blender 3.1 and having a bit of an issue with my usual work lol

First I will upload the photos

The first photo is the problem.
I pressed H to hide the vertices but the surface is still showing.
But like the second photo, it should hide the surface along the vertices.

I tried to delete the loose vertices as well but it doesn’t work.
It doesn’t affect the quality of the model, however just want to know what causing the trouble.

If you can tell me what can cause the trouble it would be appreciated.

Thank you

It’s a known bug in 3.1, there’s at least two confirmed bug reports for it in the manifest. One thing that will fix it is turning off GPU Subdivision

RIght, thank you for the answer :))
I realised that only the object created from the previous 2.9 Blender had those issues.
