Roblox Studio lagging severely upon opening certain tabs

Over the past 2 days I’ve been experiencing this bug that has been really messing with my workflow. It happens every time I open a certain tab as shown below.

I wouldn’t think this is a problem with the specs of my PC but here are my specs anyways.


OS: Windows 10

Here are the following tabs that creates the lag

  • Toolbox

  • Terrain Editor

  • Any plugins tabs Example: image

Here is the microprofiler dump

As of recreating this, I don’t think there is anyway. But I’m sure I’m not the only one experiencing this issue. This still happens with VSync disabled.


I had this happen to, the fix for me was changing the Render Setting from Automatic to DirectX, or some other option, rather than leaving it on automatic.

Edit: Mine included the Drafts tab.

Probably because you’re map is huge- it happens to me a lot.
