Recently while building a plugin UI, I noticed that UIScale causes any ScrollingFrames effected by them to lose their scroll bar. Changing the ScrollBarThickness does not solve the problem.
ScreenGui used in recording:
broken scrollbar.rbxm (24.3 KB)
System Info:
OS: Windows 11 Pro 64-bit (10.0, Build 22631)
CPU: 11th Gen Intel Core i9-11900k @ 3.50GHz
Memory: 32 GB
GPU: NVIDIA GeForce RTX 3090
Expected behavior
The scrollbar should also scale according to the UIScale property.
