When I am typing and stop for a second, a blue line (blue might be my new color scheme, thanks!) scrolls up and down. I need to wait for the line to finish to start typing again.
I turned off the simple navigator and analyze as I type. What esle could it be?
In addition, parsing is done in a thread, but updating of UI controls (the navigator tree you've shown) must be synchronized in the main thread which means it's a blocking operation. Typically this is pretty snappy, but with many nodes to refresh it will be noticeable. How large is your text? I can see it's at least 10k lines. How long is this delay?
Yeah this problem is in v17.0.134.x release (in case @marc_109 just thought it was the beta he might be using). Without switching off themes, it makes editing unusable if the navigator is open on a package with large number of funcs and procs.
