Operating system: Arch Linux
Graphics card: NVIDIA GTX 980
Broken: Blender 2.90.0 Stable Release
Worked: I'm not sure if this has ever worked correctly but it looks ugly.
Short description of error
When zooming in and out of the node viewport, the text keeps changing its size making it look like it's jumping all around. I think the view should only zoom in and out without ever changing the text's size.
Exact steps for others to reproduce the error
Add a principled BSDF node and then zoom in and out.
