Rhino 8 Bugs: Hightlighting issues of sub-object selection

Bug 1: The subobject like a curve or surface won’t be hightlighted after I use shift + ctrl to make a sub-object selection.

Bug 2(maybe?): The change I made in the print disply like the type of line cannot disply immediately, I can only see the result after restart the software (print disply is on)

I can’t repeat that here. Can you run _SystemInfo in Rhino and post back the results?

pls share a model and indicate what you are changing, then we can have a look if we can reproduce, thanks!
