HIGHLIGHTS
- Large performance hit to UpdateUILayouts as of 03/19/24 (from 0.5 → 17ms)
- Seems to be an issue that only happens to some PCs (doesn’t happen to my teammate)
- Upon resizing an element in a UI, every other element size is recalculated.
- Attached a reproduction place with the UI shown in the Microprofiles below under the private message section. I see an identical issue in that test place, my teammate still does not have the performance issue.
- “Deeply nested UI” about 12 elements deep at the most.
Recently I’ve noticed really massive UpdateUILayout jobs running in the Microprofiler. In my game, I have deeply nested UIs with thousands of elements overall. In my game in studio during a local test UpdateUILayout takes around 17ms to complete and runs every time any element in the UI is resized (seems to be worse the higher up in the hierarchy the element is). This seems like a recent issue within the last two days or so 03/19/24 and I’ve not really been able to solve the issue. When my teammate tests his UpdateUILayout, under identical conditions, take about 0.5ms.
This issue seems to only happen in studio, under any test I’ve tried Team Test, Solo Test. Running the game online runs exactly as I would expect with around 0.5ms UpdateUILayouts times.
Here’s what I see in the MicroProfiler

I’ve attempted to reinstall Roblox studio but that didn’t seem to do anything for me.
