Iterative creating mesh problem

In Rhino 7, whenever I use Hide&Unhide or Lock&Unlock or Group&Ungroup, the mesh creation process happens every time, so the operation is very slow. Why is that? As the amount of boolean computation data increases, the number of objects that need to be meshed increases, which slows things down.
Even if you open the same file in Rhino 5, these symptoms did not occur and I have never experienced this, but when I open it in Rhino 7 and Rhino WIP (Rhino 8), it occurs simultaneously in various files.
Every time I press the aforementioned tool, I have to wait for tens of seconds, so I can’t proceed with my work normally.

Hi -
I’m not seeing that behavior here.
Could you post a file that shows this on your system?

Video not playing?

Only in very limited cases, a video might help figuring out an issue. This isn’t one of those cases.

Because it is a copyrighted design, only part of the object is attached. There will be no problem in checking the symptoms.

File attached. Are you reviewing?

Thanks. I’ve put this on the list as RH-74422 Display: Creating meshes again and again
