Plugin GUI updates unrealistically laggy

Bug Reports Studio Bugs
#1

Reproduction Steps
Create a plugin GUI and place a container of list items inside the frame. This best happens with my own plugin, Browser

While not as laggy, this also affects Roblox’s QWidgets.

System Information:
CPU: Intel Core i7-9750H CPU @ 2.60GHz
Memory: Unknown, 8GB
GPU: NVIDIA GeForce GTX 1650

Beta Features enabled:
Adaptive Timestepping
Luau Powered Autocomplete
Parallel Luau
Script Version History for Non TeamCreate games*
Scripts are Non-Strict by Default
Terrain QoL Updates*

* I didn’t opt into these (but thats a bug report in it’s own right)

Expected Behavior
The plugin UI should update without massive lag spikes.

Actual Behavior
The plugin has a massive lag spike before updating, the plugin also appears stretched for a second or two. This gif is running at 30fps without slowdown from Windows.

What I believe is happening is, Studio is updating components that aren’t being rendered resulting in massive lag spikes, even if the component’s Visibility is false.

Don’t know, doesn’t happen with me. Have you tried re-installing studio?

We’re experiencing something like this too. We have a bunch of stuff in ServerStorage that isn’t being rendered but seems to make studio really slow.

When we delete the items, Studio goes a lot faster.

I think we need a new thread for this. Can any Regulars open one?

I’m also experiencing this with my plugin. Anything that’s being moved with lots of UI Objects inside of it will create a huge FPS drop (even when opening an empty place during loading when the plugin isn’t even opened) :confused:

This is fixed all of a sudden? Did someone on the engineering team actually fix this, considering how Studio got an incremental patch.

#7

Somebody must’ve fixed it because for months, simply resizing a widget would drop my fps from 60 to around 20. I messed around with a widget the other day however and noticed absolutely no noticeable drop in frames, although I’m a bit curious why that problem got fixed for me, but not for some other users…
