Can you still reproduce this in 4.0.3 and 4.1-beta3 or later?

[B-l-u-e-f-i-r-e]

Yes, I could still reproduce this issue in Godot 4.0.3

Not reproducable in Godot v4.3.dev (f8a2a91) - Windows 10.0.22621 - GLES3 (Compatibility) - NVIDIA GeForce RTX 3060 Ti (NVIDIA; 31.0.15.4601) - 12th Gen Intel(R) Core(TM) i7-12700F (20 Threads)

Can someone confirm this on 4.1.3 or 4.2.1? Otherwise this can be closed as fixed (otherwise the specific PR solving this should be identified and possibly cherry picked)

Tested on Windows 10 on 4.2.1; experienced inconsistent latency in a brand new project. It ranged from being instant, to taking 15 seconds, to taking an indefinite amount of time. Toggling visibility instantly changes canvas, as well as zooming in/out.

[EAinsley]

Reproducible on v4.3.beta.custom_build [93fc9b8] (on Windows 10).
Note that the Canvas Layer updated after scrolling the mouse (the purple line moved), but children didn't update. After change the visibility, the child was resized.
