minimap has a fatal bug.

Currently, the minimap has a fatal bug. The problem is that the entire Goneovim application will randomly freeze if you continue to operate the application while the minimap is displayed.
#450 is a related issue.

I am investigating this issue but do not know the root cause.
The results of the analysis by go-delve show that the values are not received in the channels created inside neovim/go-client and remain in a waiting state. This can be understood as no response from Neovim as a result of executing the API to Neovim.
On the other hand, if it freezes, it is likely that there is a more fundamental problem hiding behind it, since it occurs in the same processing each time.
