Quick Summary

As of 2026-03-22, the Roblox Developer Forum topic "I'm seeing strange "lines" in Roblox Studio" shows 4 posts and 3 participants.
This looks like a Roblox Studio visual overlay problem, not a broken game file.
Best first move: check Studio Settings display toggles before reinstalling anything.

What's New

Community report snapshot (2026-03-22): A creator asked what the lines are and how to turn them off in thread #4530190.
Related solved case (2022-07-05): In a similar Roblox Developer Forum thread, turning off
Code: Select all
```
Physics > Display > Are Anchors Shown
```
removed the lines.
Extra context (2020-09-17): Another Roblox Developer Forum post explains that toggle is for showing anchored/unanchored parts, so accidental enable can make weird line overlays.

Developer Context
This is most likely a debug-visualization setting issue inside Roblox Studio, based on related Roblox Developer Forum posts from 2020-09-17 and 2022-07-05.
Inference: these line visuals exist to help creators debug physics states quickly, but when enabled by accident, they can look like "glitch lines."
As of 2026-03-22, no official Roblox release note is linked in the thread facts you shared.
Why You Should Care
If you build on the Roblox platform, this saves you time right away.

You do not want to waste hours fixing parts that are already fine.
Creators can keep momentum, and teams can avoid fake "bug panic" in testing.
FAQ

Q: Are these lines a virus or hacked model?
A: Usually no. First check Studio visual/debug settings.
Q: What setting should I test first?
A: Start with
Code: Select all
```
Physics > Display > Are Anchors Shown
```
and other display overlays.
Q: Will players see these lines in my live game?
A: Most of the time this is Studio-side visualization, not a live gameplay issue.
Q: What if turning that setting off does not fix it?
A: Reset Studio settings, disable plugins one by one, then retest in a blank baseplate.
Q: Is this confirmed for thread #4530190 yet?
A: Not confirmed from the thread facts alone. It is the best evidence-based first fix from related DevForum cases.
