Original GitHub issue: https://github.com/moghtech/komodo/issues/680

I have noticed for the past several weeks a strange behavior: after I sync a pending Resource-Sync to my GitHub repo, the UI becomes unresponsive.

I am using Edge on a Windows PC with tons of RAM and plenty of power. This seems to consistently repro each time:

Go to Resource-Syncs
If there is a pending change - commit the change
UX refreshes (such as alert in the top right no longer shows there is a pending sync) - however the UX becomes completely unresponsive. If I try to click on anything I get an alert from Edge that the page is not responding. This does not seem to resolve and I end up closing the tab completely.

I think I need to remove the fancy syntax highlighting for the TOML. In edge case it causes this UI freeze.

It is sad because this syntax highlighting is nice. But the way you make syntax highlighting with monaco editor is incredibly confusing and I have no idea how to debug this issue. The code is here: https://github.com/moghtech/komodo/blob/main/frontend/src/monaco/toml.ts

Are you using the same syntax highlighting on the Stack Info page (and perhaps elsewhere?) Or are you using a different type/feature (like a diff view perhaps?)

The syntax highlighting depends on the language, stack info uses standard Monaco yaml highlighting. On toml / sync syntax highlighting has this issue.

It does seem to be that, as for my at the moment the page will freeze if I have the Info tab selected, which of course has the highlighting.

The highlighting is really cool too :(

Starting in 1.19.0, the fancy TOML highlighting is disabled by default to avoid this issue. If your setup works with it, you can enable it again with KOMODO_ENABLE_FANCY_TOML=true
