Automatic sized UI going crazy - jiggling and rescaling

[chickenputty (Adam)]

Today we are receiving a lot of reports about UI breaking. It is happening to automatic width elements that are constantly rescaling making them jiggle uncontrollably. It happens when scrolling, and looks worse the bigger the resolution. It happens in Studio, Windows, and MacOS. Seems to be an update to Roblox that caused it. I do not believe we changed anything.

I’ve shown the setup of the UI in private

If this happening only in studio? It may be a similar problem to what I am facing.

Flickering UI Elements ONLY in Studio

When testing the game in studio, creating a slideup window for my UI causes the elements to flicker. The flickering element is a TextButton with a UICorner and padding. I think the cause of it has something to do with the UIListLayout and its HorizontalFlex property. This bug doesnt occur in game, and I’ve tried to restart both Studio and my computer, M1 Macbook Air. Both studio and the game are running the same version published, with no changes between them. If anybody has any suggestions on…

Flickering UI Elements ONLY in Studio

This also causes my studio to indefinitely hang when not in Play mode. This issue last occurred roughly 4+ hours ago in multiple sessions on a Windows 11 Desktop PC. repro.rbxm (7.7 KB) — Insert into StarterGui Selecting the Frame or the TextLabel in this model will freeze studio. Changing the Text from “XP: 200” to → “XP: 199” for example resolves this due to the size difference. Selecting will not freeze studio if the ScreenGui.Enabled is set to false I’m not using any UIFlex features.
