Due to the use of a private Apple API, apps with older versions of Electron cause systemwide lag on macOS Tahoe. Logic 2.4.39 appears to still be built with Electron 27.1.0, which has this bug. The problem code was introduced in Electron 9.x.
When acquiring data, systemwide lag is highly undesirable. Would it be possible for the Electron version used by Logic2 to be bumped to a version that patches out this bug?

>
> Using an M1 Max MacBook Pro, having Electron-based apps open / not minimized causes a huge lag.
> CPU and GPU usage remains low, but if I have Discord and VS Code open, moving windows, scrolling is stuttery. It happens even when only Discord is open but it gets worse if I open a second Electron app.
> This is kind of weird because while having Discord open and I'm in Chrome, the lag still occurs, but it's fixed if I minimize Discord (even though Chrome is fully in focus and maximized). This happens since upgrading to macOS 26 RC, macOS 15 didn't have this issue.
> There is a similar lag if I open Settings - Wallpapers, moving the Settings window is laggy then (looks like 60fps instead of 120).

Hi @david2,
Thanks for reporting this. We’ve heard a few reports of this so far and about 2 weeks ago we kicked off an internal project to update to the latest version of Electron. Sorry it’s not out yet! We ran into a few issues - updating to the latest electron also requires us to update some packages and node native modules to support the newer version of Node, and unfortunately it’s turned into a project, and I had to put it on hold while working on getting the last release out. I hope to get back to this soon.

Hi Mark,
any news on this one?
Best regards!

I’m sorry that those links won’t help fixing Logic but I hope they help users.)

Supposedly macOS 26.2 will work around this. Probably still a few weeks out.

@saleae_forum @david2 Thanks for your follow ups! Is there any chance you’ve managed to reproduce this issue using our software? We haven’t been able to.
Updating to the latest version of Electron is a bit of a project as Mark mentioned previously.
We’ve tested the issue as described in the comments on the PR here ([https://github.com/electron/electron/pull/48376](https://github.com/electron/electron/pull/48376)). Our tests were performed on two apple silicon macs with the latest MacOS release, but I suspect we might need a higher refresh rate monitor to detect the problem.
If you’re able to reproduce it, that would help us prioritize the rest of the work to get this update going.

Apple has implemented a workaround on macOS 26.2 which was just released today, so this probably can be deprioritized for now.
