The Electron issue plaguing macOS 26 Tahoe isn’t something a user can fix. Aside from downgrading back to Sequoia, which is likely more trouble than its worth, it is better to keep Electron apps at arm’s length. If it is constantly running in the background, such as 1Password (fixed), it is best to voice your concern to the developers. For others, it is likely more practical to simply stop the an affected app from running longer than it is necessary until the fix is issued.

I thought to write this as a PSA piece, but there is also a great web app that could help along the way. Long story short, Electron framework, known to be used for desktop apps for cross-platform compatibility and web app likeliness, has a bug that causes GPU performances issues on macOS 26 Tahoe. The developers behind the Electron have already issued a patch on their end, now the balls are in the hands of app developers that used the framework.
