After calling the standard graph the first time after starting Obsidian, I see it with all nodes and edges as it should be. But after some using application in the next graph calling, I see just nodes without any edges. The links between nodes do not show. Sometimes they are beginning showed after full closing of the application. But mostly only after rebooting the system. It happens in both cases with white and with black themes.
Typically losing just lines between nodes, the arrows are shown in the right direction.
Operation system: Windows 7 sp 1
