[Fixed] Polygon groups (AUG 23)

Hi IStonia,

You made changes to the handling of the polygon groups in Aug-23 release.
It appears to of caused an issue.
Example:-
When working with an imported object with muliple polygons groups, if I start to delete polygons that belong to groups, Nvil becomes unresponsive, with it using full(single) core, and memory usage increasing slowly. I eventually have to kill Nvil process.

Working with same model/mesh, imported without the groups, no issue.

Please check when you have time.

It appears to be more of an issue than just with groups.

I am seeing times where viewport will be unresponsive for 2-3 seconds, usually after closing streamline/composite tools window, or when attempting to selected(add) polygons(LMB) to a selection.

It is unpredictable, and I am unable to find a specific reproducable example.

I'm experiencing the same problem:

The Aug-23 version seems to freeze randomly (for a limited time at first) when I'm working with Draw Mesh. After it happens for the first time, all rectangular selections will cause another long freeze and even crash-to-desktop with no errors.

Yep crashes happens also to me. I had to switch back to 22.Aug version...

Should be fixed.

Not seeing any issue with groups up to now.

I have seen some issues, but it may be a problem with my config. I have started a new config, so will know in next few days.

Thanks,
