Inconsistent grid points when changing screens

[2nOrderEDO]

Hi @hanspi42,

I wanted to thank you for creating this very useful software.

I've encountered an issue that I'd like to report. When I open a saved graph on a different PC with a different monitor and resolution, the snap grid is displaced, causing all nodes to shift out of alignment with the grid. This is a minor inconvenience, as I need to manually adjust each node to snap back into place with the new grid position every time I change computers.

Steps to reproduce:

1. Save a graph on one PC with a specific monitor and resolution.
2. Open the saved graph on a different PC with a different monitor and resolution.
3. Observe the grid displacement and node shifting.

Expected behavior: The grid and nodes should maintain their original positions and alignment, regardless of the PC or monitor used to open the graph.

Thanks for your attention to this issue!
