Zotero 10.0-beta.5+b7437faf5
macOS 26.5 (25F71)

Reading OCRed vertical-text Japanese document. This one document causes massive lag spikes.

*Appears* to correlate with this Error Console output:

Error: Failed to load resource://services-settings/remote-settings.sys.mjs BTPRemoteExceptionList.sys.mjs:27:5
Warning: Cannot load system font: MSGothic, installing it could help to improve PDF rendering. pdf.mjs:359:13
Warning: Cannot load system font: MSMincho, installing it could help to improve PDF rendering. pdf.mjs:359:13

Any help with diagnosis and troubleshooting would be much appreciated. Thanks!
