[bug] TAURI UI NOT WORKING PROPERLY AFTER SYSTEM AWAKE FROM SLEEP.

[Sampaths4u]

Describe the bug

I have authenticated my tauri app and then I am hiding tauri UI. Then after my system went to sleep and will awake and then my UI code with hooks UseEffect is not working and also not sure whether UI code is loading or not. Tried with tauri:run event: resumed even this is not called after awake from sleep/hibernate.
I have dual monitor. Tried visibility/ focus nothing works. What is the event for sleep in rust or react to handle

I am having a similar problem. My Rust backend is working fine after waking from sleep on MacOS but the UI is stuck. I can't even select different tabs in the developer tools without serious lag. I only have a shell of an app so far that is sending a simple message from the backend to the front every 5 seconds. There is no other work going on yet to slow the app down.

same, I think I will have to manually restart all after a wake-up event.

We're experiencing this in our Tauri v2 app (screenpipe) on macOS — after sleep/wake, WKWebView's content process gets killed by the OS and the window renders as a black rectangle.

Our workaround: poll NSWorkspaceDidWakeNotification (we already had a sleep monitor for other reasons), then after a 3s delay to let the display stabilize, reload all webview windows via window.eval("window.location.reload()").

Not perfect (brief flash on reload) but it recovers the UI automatically. Would be great to have a proper webViewWebContentProcessDidTerminate handler at the wry/tauri level so apps can respond to the content process dying without polling.

That's coming very soon #14523
