Operating system

macOS

Joplin version

3.4.12 (prod, darwin)

Desktop version info

Joplin 3.4.12 (prod, darwin)
macOS 26.0.1

Tested via https://gist.github.com/tkafka/e3eb63a5ec448e9be6701bfd1f1b1e58 it turns out that Joplin uses Electron 35.7.5 (Contents/Frameworks/Electron Framework.framework/Versions/A/Electron Framework), an Electron version that "_is overriding a private AppKit API (cornerMask) to apply custom corner masks to vibrant views" (see electron/electron#48311 (comment))

The specific Electron versions that contain the fix for the issue are v39.0.0-alpha.7, v38.2.0, v37.6.0 and v36.9.2 🙇‍♀️ (from electron/electron#48311 (comment))

Please update the underlying Electron version.

I believe pull request #13445 has already addressed this and this change should be included in the v3.5.5 Joplin prerelease.

It's 64 days since the last release and 9 days since macOS 26.1 release, your software assurance seems a little excessive to me
