Electron framework leading to Tahoe slowdowns

Recent discussions have identified an issue with the electron framework leading to significant slowdowns in Mac OS 26 (Tahoe). 

You can see a good description of the problem here:https://mjtsai.com/blog/2025/09/30/electron-apps-causing-system-wide-lag-on-tahoe/

And this page offers scripts to identify apps that use the _cornerMask to draw drop shadows for windows in Electron apps (which triggers the slowdowns through WindowServer): https://gist.github.com/tkafka/e3eb63a5ec448e9be6701bfd1f1b1e58#file-detect-electron-apps-with-macos-lag-sh

I played around with he scripts and it looks like 1Password 8.11.12 is one of the affected Electron apps…

I'd be great to tweak the embedded framework (or use one of the newer, corrected frameworks) to eliminate the issue in 1Password :-)

    Hi cortig​ and MitoWorld​,

    This should be resolved in 1Password version 8.11.14 with the move to a newer version of Electron. Please let us know if you're still seeing performance issues.

      Is this why on macOS Sequoia, quick access and SSH prompts no longer have rounded corners? Is there no way to have rounded corners without running into this bug?

        Hi PatientHawk​,

        This is related, but we have a fix currently being tested in the latest beta, so things will be nice and rounded again soon!

      Yep. It's using Electron 38.2.0 which doesn't have the issue. Thanks!

    Thanks for the information (and macOS is up to date on my Mac indeed).

    I just enabled nightly, bt it doesn't look like the present one incorporates the fix/workaround. It's still using _cornerMask in the Electron framework 37.3.1.

    I'll keep my eyes open for new builds though :-)

      Oops, sorry, cortig! I think it hasn't actually hit the publicly-available nightly yet. I've updated my response so I don't throw off anyone else. We are working on this, though!

    Hi cortig​ 👋

    This is definitely on our radar and we'll be moving to a newer version of Electron! If you haven't already, I'd also recommend updating to Tahoe 26.0.1, as it fixes an autofill bug that was causing some performance issues.
