Graph Lines not Displaying -- Windows 7

Hello! I picked up Obsidian yesterday, and it’s working great, apart from one issue: after some time using a vault, the graph will fail to display the links connecting each node. The links are still present, and when enabled, the arrows still render, but the lines themselves fail to. Upon creating a new vault and importing my previous files, the error appears to subside temporarily, but tends to come back again after a bit of use.

I’m currently using the most recent version (v0.12.19) and have installed no external plugins or themes; the issue persists between the base light and dark modes, and my OS is Windows 7 Ultimate Edition. Thank you for your support.
