Block positions and connections in flowgraph change on different machines

Hi guys,
how do you manage working on the same flowgraph in GRC while using different machines?
While the flowgraph and each block’s position seem pretty decent on one PC, blocks aren’t aligned and connections aren’t straight when opening the same file on another PC, even though they run the same GRC version. They sometimes even overlap, which is annoying when you have to work on larger projects.
I didn’t find the right settings in the config file. Is there anything I can do to fix this issue or is this a known problem when it comes to teamwork using GRC?
