Developer Context
This looks like a bug-status update, not a planned feature patch.
On 2026-04-01, the Roblox Developer Forum thread had 1 post and 1 participant, and it was in "Welcome & Introductions", so it may not have high visibility yet.
There is no official release-note link in that thread yet.
My best player guess (not confirmed): the click path for sky/locked-hit checks may be doing extra work and causing frame drops.
Why You Should Care

• Builders click empty space a lot, so this can slow your whole workflow.
• If your map uses many locked parts, editing can feel way worse than normal.
• Fast workaround right now: click real selectable parts first, use Ctrl+click to clear selection, and avoid spam-clicking sky while editing .
• If you post reproducible steps and a short video, devs can test faster and fix faster .

FAQ

1. Q: Is this a full Roblox platform crash?
   A: No. This is a Roblox Studio editor lag report, not a game-server outage.
2. Q: Does lag happen only when something is selected?
   A: In the 2026-04-01 report, no. It also happened with nothing selected.
3. Q: Did reinstalling Roblox Studio solve it?
   A: Not in this case. Reinstall was tested on 2026-04-01 and lag remained.
4. Q: What should I do while waiting for a fix?
   A: Use object-first clicks, Ctrl+click unselect, save often, and record a quick repro clip if you can.
5. Q: Where should I report extra details?
   A: Add your repro steps, PC specs, and video to the same Roblox Developer Forum topic so all evidence stays in one place.
