Auto-complete not working in full screen on second display (macOS)

M_etrics · September 3, 2025, 6:16pm

Platform:
macOS (Tested on M4 Pro and normal M4 Air)
Roblox Studio (latest version as of September 2025)

Summary:
When using Roblox Studio on a second display in full-screen mode, the auto-complete/intelliSense feature (e.g., for Lua scripting) fails to appear or function properly.

Actual Behavior:
When Studio is in full screen on a second display:

The auto-complete window does not appear at all.

This makes scripting difficult or impossible when using Studio in full-screen mode on any external monitor.

Workarounds:

Resizing Studio to windowed mode resolves the issue.
Keeping Studio on the primary display also resolves the issue.

Steps to Reproduce:

Connect a second display to your Mac.
Open Roblox Studio.
Drag the Studio window to the second display.
Enter full-screen mode (green maximize button).
Open a script and begin typing code that would normally trigger auto-complete.
Observe the lack of auto-complete suggestions.

System Details:

macOS: Sequoia 15.6
MacBook M4 Air and Pro
Roblox Studio Version: 0.688.1.6880864
External display: General display, consistent across my 3 owned displays.

Expected behavior

Auto-complete should appear near the cursor and provide suggestions as expected, even when Roblox Studio is running full screen on a second monitor.

Example
Outside of full screen:

In full screen:

Hi @M_etrics thanks for reporting!

We’re not able to reproduce this on our side. To better understand the root cause, could you try the following:

Right-click in the script editor — does the context menu pop up?

Hover over the error in the script — does the tooltip appear?

Right-click on the top bar — does the context menu show up there?

Thank you!

No, it does not.

No.

No again.

However autocomplete works on enter being pressed, I just cant see what is being autocompleted.

Hi @M_etrics

What beta features are you enabling? Can you try to disable all of them?

Also, do you have any plugin install in Studio? Can you also disable all of them as well?

Thank you!

Hi - disabling beta studio features fixed it. next gen studio preview was the culprit. @yohooyohoo

M_etrics · September 13, 2025, 4:38pm

@yohooyohoo Are you going to forward this internally to patch or shall I reverse the beta feat until future notice?

yohooyohoo · September 13, 2025, 9:20pm

I’ve forward this to the team and they are actively working on this. In the meantime, I recommend to disable this beta feature for future notice.

Just want to confirm - as long as you enabling “next gen studio preview”, you cannot see any popout tooltip and menu, right? If you can, would you also try to right click on Explorer widget and maybe other widget, like 3D main view?

M_etrics · September 14, 2025, 8:10pm

Can be seen in both beta and reverted beta versions

M_etrics · November 25, 2025, 5:30pm

Is there any update as I believe next gen was released?

Hi @M_etrics, we haven’t been able to reproduce this issue on our side. We’ll update you if we find a way to reproduce it. In the meantime, could you try disabling the beta feature or using non–full-screen mode? Thank you!

Disabling and non-full screen mode both resolve, but of course, are inconvenient.
