After the 2025 update:
complex and heavy models, organized with many tags. Scene with few turned on tags. I rotate the model, and the graphics card (nvidia rtx A4000) in difficulty hides the objects showing only the bounding boxes. The fact is that it shows the bounding boxes even of objects that are in turned off tags.
If you have part of a group, with raw geometry tagged and the group containing that raw geometry with a different tag, this can happen. Or more likely ungrouped raw geometry with each face on different tags. then hide a tag of part of the touching geometry, then select visible geometry and try to rotate… I believe that would create what you describe
Normally I work with faces and edges in tag 0. Groups and components assigned to their respective tags. And nested groups.
I have to say that until before installing skp2025 I had never seen this thing.
However, it happens with complex models, when the graphics card is ‘forced’ to hide the pieces of the model replacing them with bounding boxes.
It could be that with other models the graphics card maintained the display, and without bounding boxes I did not notice that groups in turned off tags were also processed.
