This issue occurs with the rendering of SurfaceGuis which are AlwaysOnTop, in FixedSize mode, and have a small CanvasSize.
The attached file contains SurfaceGuis with a small CanvasSize on the Y axis.

System info (expected overshooting behaviour):
AMD Ryzen 5 2600X Six-Core 3.6 GHz
NVIDIA GeForce RTX 2070. Driver version 18.104.22.1685
Memory 16 GB
System info (inconsistent overshooting behaviour):
Intel Core i9-10900K 3.70 GHz
NVIDIA GeForce RTX 2080 Ti. Driver version 22.214.171.1245
Memory 64 GB
The SurfaceGuis should
a) never overshoot their adornee if CanvasSize on one axis is smaller than 1
b) have consistent overshooting behaviour across different clients.
Here is a visual example of what b) should look like on both clients:
The SurfaceGuis overshoot the adornee when CanvasSize is smaller than 1. If the overshooting itself is not a bug, then I assume this is intended behaviour.
The inconsistent behaviour is that some clients see the image given above, and some see the following:
It seems to be difficult to reproduce the latter, only one person on our team gets it, and it only happens for them in a live game. (Their system info has been labelled ‘inconsistent overshooting behaviour’.)
Increasing CanvasSize on that axis to be >= 4 (based on what we can see from the two different screenshots).
