Selecting instances on Studio is super slow

Pretty straightforward: Whenever I select instances in ROBLOX studio, it freees the entire thing for like half a second. If I move my mouse at all during that time, it’ll behave as though I was clicking and dragging and move any parts I might have tried to select.

I’ve started having this issue today.

Repro is simple: Keep a Studio window open, work in it as you usually would for about 5-10 minutes, and notice how it gradually slows down.

System specs:

  • Windows 10, latest updates (obviously)
  • 64 GB RAM
  • Hyperthreaded Quad-Core i7 @ 2.6 - 3.2 GHz
  • ROBLOX is installed on an SSD

I’m not able to notice any anomalies in terms of CPU/RAM usage or other system utilization when this happens. It just freezes and comes back a split second later, after moving a few things I didn’t want moved.

I’m also experiencing this, Studio is practically unusable right now.

EDIT: It only seems to occur when I have the game window open. If the only thing open is the script editor it works fine.

Seriously slow, unable to use it right now. Takes a second or two to select anything, opening scripts is insanely slow and moving things is hard to do at all.

(Not sure if any of this matters but ?)

When this happens, can you hit Ctrl+F6 and post a screenshot of that?

Yes, will do next time I encounter the issue.

Seems to be UpdateToolbars having a heart attack.

UpdateToolbars typically takes some time after a click. That code is what updates the window to reflect selection changes (as well as other things). Do you encounter similar problems in an empty baseplate? This may be a symptom of a large number of parts as well.

A bunch of unions.

There’s a noticeable jolt when selecting things on blank baseplate files that I don’t remember occurring before, although it’s significantly less jarring than on a file with stuff in it.

That tiny jolt has always been there, but typically on-click most users won’t notice it as they expect some brief delay. The large jolt is more concerning, but seems to be because of a large number of parts. Just to make sure, can you send me a video of this happening to you in a baseplate with Ctrl+F6 open as well?

Can do.

Additional info, the jolt on the blank baseplate gets significantly longer the more you select things.

Accidentally recorded audio, might be loud. ¯\_(ツ)_/¯

Same sorta thing.

@Letink That looks like the expected delay I mentioned before. It’s a side-effect of how we handle updating.

@TwentyTwoPilots That’s certainly unusual. Do you have any plugins enabled? Do you have another machine to try that on?

Yea I’ve got a few plugins enabled. I don’t have another machine at my disposal but if you want, I can disable the plugins that show up in Plugin Manager and try it again.

Try disabling/removing all plugins and see if that helps.

It’s happening to me too.

I haven’t installed or updated anything in days.

I can send a video when I get home.

Removed all plugins, didn’t make a difference.

You can’t see it in the gif but there’s a large stutter, it only ever occurs when selecting stuff. The more you select the worse it gets in time.

Yeah, this is also happening for me too. Ths whole studio just feels slow/laggy!
