Short description of error
When dragging a node link, it turns invisible

Exact steps for others to reproduce the error

  • Open default startup file
  • Go to the geometry nodes tab
  • Create a node group
  • Drag from a node socket to create a node link
  • It is invisible

I bisected this problem to 9d3f35a0bf1bf5776363bfd61d53a7c85b5827a4, maybe there was a mistake in the revert revert?

Ah yes will work on it tomorrow. Would assume it is related to drawing a single nodelink (none instance shader).

This still occurs in this Blender version:

Although, now there's sometimes a visual glitch upon trying to connect the node link to another in-/output. A very small, line flickering, randomly, or, occured once on my pc, a thick stripe of different colours briefly flickering offset to the actual node link (didn't get it on screenshot or vid).

I just updated via Steam, and it still occured. I have the newest version available on Steam.

Steam hasn't been updated. That is done tonight around 2am.
