System Information
Operating system: Windows-10-10.0.22621-SP0 64 Bits
Graphics card: NVIDIA GeForce RTX 4090/PCIe/SSE2 NVIDIA Corporation 4.6.0 NVIDIA 546.33

Blender Version
Broken: version: 4.3.0 Alpha, branch: main, commit date: 2024-09-22 23:31, hash: a34b0e17d624
Worked: 4.2

Short description of error
Usually, when a node is not selected, user could use the tweak tool move the node with on click.
Uncheck "Load UI" in preference causes failure in direct nodes manipulation.

Exact steps for others to reproduce the error

  • Download startup.blend
  • Open the file and go to the Shading tab.
  • Notice that you can click and drag on a node and it will shift that node.
  • Open Preferences and disable Load UI. This can be done by following these steps:
    • Select from the top of Blender Edit -> Preferences
    • Go to the Save & Load tab.
    • Disable the option Load UI
  • Reopen startup.blend by dragging it into the current Blender window.
  • Notice that you can not click and drag on nodes anymore. You have to click on a node, then let go, then you can drag.
  • Manually re-selecting the select tool in the tool bar of the node editor fixes this issue.

I am personally unable to reproduce this issue. Using the steps shown in the video. And here are my interpretation of the steps:

  • Open Blender
  • Open Preferences and disable Load UI
  • Press Control + N to open a new file, and notice that you can't directly move nodes anymore. You have click on them then you can move them.

A possible cause for this is the custom startup file you have. Are you able to share it with us? The file should be located at:
C:\Users\YOUR_NAME\AppData\Roaming\Blender Foundation\Blender\4.3\config\startup.blend

As a side note. I believe this is a similar issue to #126990

The default node editor tool (the select tool) probably isn't activated when you load your file with Load UI turned off.

Exactly.

I'm using a portable startup file. Here you go.

Using the attached file, I can reproduce the issue.

It appears to be different from #126990.

I will mark as confirmed and high severity as it is a regression, and can look into bisecting what caused it.
