Zotero using 50% CPU (on my Mac) unless minimized

Today I noticed that Zotero (both on 5.0.78 and 5.0.79) uses constantly around 50% CPU on my Mac (10.14.6).
Unless minimized — then it only uses 2.5-3%.

For doing nothing, mind you. Sync is done, and if I enable Debug Output Logging, nothing is logged while using 50% CPU. Funnily, if I minimize the main window but not the log window, CPU usage goes to 5-6%.

This might have gone on for a while; this is 50% usage of *one* core, so the computer stays relatively silent even while Zotero is open.

On 5.0.79, I submitted the debug output (with Debug ID D1990128699).

Installed extension (from the debug output window):
> version => 5.0.79, platform => MacIntel, oscpu => Intel Mac OS X 10.14, locale => en-US, appName => Zotero, appVersion => 5.0.79, extensions => ZotFile (5.0.14, extension), Better BibTex for Zotero (5.1.168, extension), Zotero LibreOffice Integration (5.0.20.SA.5.0.79, extension), Zotero Word for Mac Integration (5.0.24.SA.5.0.79, extension), Shockwave Flash (, plugin)

    It's using ~0.0% for me when idle on 10.15.1. Does this happen immediately after a Zotero restart? Does it happen if you disable ZotFile and Better BibTeX?
  • Thanks. The issue appears iff I enable Better BibTeX. I'll ask there.
