- Avarayr's tracker of affected and fixed Electron apps
Fixed versions:

Run
launchctl setenv CHROME_HEADLESS 1on every system start. The CHROME_HEADLESS flag has a side effect of disabling Electron app window shadows, which makes them ugly, but also stops triggering the issue.

🌦️ Weathergraph is my weather app that shows hourly forecasts as charts instead of lists. See a week's worth of temperature, precipitation, wind, UV, and pressure in a single visual.
Built in Swift/SwiftUI for iPhone, Apple Watch, and Mac. Highly customizable if you're into that.
"I first downloaded the app because I caught sight of the large complication on an Apple Store employee's Apple Watch and asked about it. This is the perfect weather app. All information beautifully presented and easily accessible." - lucenvoyage
Thanks! Tomas
