The bug happens in ScreenGUIs which use an UIScale object in a Frame with multiple GUI objects. When we change the Scale property to something considerably bigger or smaller than 1 (for example 0.5 or 2), some of the GUI objects in that frame disappear and won’t be displayed until we set the Scale back to 1, ignoring the properties like Visible or ZIndex. Normally, it’s expected that all of the GUI objects in that frame will be shown always regardless of the Scale value in the UIScale object.
This bug happens always when I try to replicate it. It’s not place-specific. Here’s an example place with my map GUI which is severely affected by this issue: UIScale bug.rbxl (27.3 KB) (you need to run it in play solo mode and click plus or minus buttons in the GUI to change the Scale property).

My graphics card is Nvidia GTX 1050ti.
This issue has been happening just for a few days. In that time, my map GUI wasn’t updated in any way, so I believe the reason of this is definitely on Roblox’s end.
