Rhino 8 lags when selecting object

Hi,

When selecting an object from “select object” popover window in the model space, which usually shows up where selecting amidst several objects overlapping in view, there is always about a second of lag whether I actually select an object or none. During this lag I no commend or view orbit would work. This doesn’t seem to be a performance issue as I can select very complex objects with no lag if selected directly without triggering the select object popover.

Updating to the latest R19 release candidate 2 did not remove this issue.

hi @taektonic
pls run _SystemInfo in Rhino and post back the results. Does this happen in all models? Also when you draw, say, a couple of boxes on top of each other?

Hi @Gijs
This hang only occurs when selecting object through the popover window, not when an object is directly selected. This happens on all models including a simple scene with two boxes that I try to select one of them when viewport shows them overlapped in view and object selection window pops up when trying to click on one.

Attached is the sysinfo data I just queried.

@taektonic does this happen as well when you disable Enscape and restart Rhino?

@Gijs I just tested it with Enscape disabled and Rhino restarted. The lag persists even so. Not sure if you have access to a Mac with M series chip, but I wonder if this is something you could test on your end… Simply by having several objects overlap in viewport with Ghost view on so you can see other objects through one another, then trying to select something that would toggle the object selection popover, and selecting one from the list or none to see if there is small lag if you try to orbit view immediately upon selection.

Thanks.

I cannot reproduce that issue here (On M3 Max running Sonoma 14.7.1)
I’ll ask a colleague to see if they can reproduce

I cannot reproduce this issue here with the following configuration:

  • MacBook Pro M4 Max
  • macOS 15.4
  • Rhino 8 for Mac (8.19.25107.01002)

Here is what I’m doing:

  1. Starting a new modeling window.
  2. Running Box and drawing a box in Perspective.
  3. Maximizing Perspective.
  4. Selecting the box and running Copy and copying the box 5 times right on top of itself.
  5. Using left-click to select the box(es)

The Object selection popover appears instantly.

@taektonic I’d be curious if you see this lag in 8.18 or not. We’d like to get to the bottom of this.
