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 how to fix this I’d be very greatful as this hinders development a good amount. Please note that this topic is being posted here as I dont have access to bug reports.
Hello there, I’ll attach a roblox place file below for reproduction purposes. I also want to add an observation that selecting the flickering element in the explorer causes the flickering to stop, however the SpaceBetween horizontal flex doesn’t recalculate properly, and then toggling to a different setting and back causes the flickering to start again.

To reproduce click on the test application icon and then click create slideup.
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 – Studio only seems to freeze if the Gui Inset properties are set similarly to this.
It looks like this is being caused by the specific value of UIScale.Scale, I tried different scale values other than 0.784 and that seemed to stop the flickering?
A temporary workaround could be setting RichText=true on the TextLabel.
This bug looks to be with flex layout, since it only occurs if the flex beta is turned on. I’ll take a look and let you know when it’s fixed.
Some possible workarounds could be to turn off TextScaled on your TextLabels or avoid using flex layout, since I think this combination is causing the issue.
