In LabVIEW 2021 SP1, the automatic layout of wires when moving diagram objects is disabled if "Enable automatic wire routing" is unchecked in Tools>>Options in the Block Diagram category.
LV2021 has a new "feature" called "Auto-Routing" (this is not Auto-Wiring, which can be deactivated in the options!). Auto-Routing moves wires around if you touch for example Sub-VIs.
Especially in compact VIs this function is a disaster right now. Sometimes for example wires will go "through" Sub-VIs so that an output leaves the Sub-VI at the wrong side resulting in a VI which is terrible to read:

2. Same snippet, I just moved the "Get Variant Attribute Function" by one pixel to the right:
First we thought this is a bug, but the support told us it is a feature. But please: Let us deactivate this "function" in the options. I have colleagues telling me they would stop using LabVIEW if this remains as it is right now.
