Verbum 22.0.23; Mac latest.
Happened after the last update (I fudged, and turned updates back on; big mistake).
Anyway the bug looks like the bug at Logos 10 intro ... a delay of about 3 secs between selection, and showing the highlight. That bug got fixed but is back. Most people probably won't see it ... related to large layouts, I think.
Also, when a resource is opened (added to layout), there's no highlights, until I highlight (with delay). Then they all show up at once.
I decided to avoid the bug, by just deleting all my highlights (about 63,000). Sounds drastic, but I only use highlights for visual memory; I delete periodically.
That didn't help (a day later with re-starts, etc).
I assume this bug is here to stay. High-speed MacM1; the code must really be churning.
