Description
Hi!
Recently, GTK4 support was introduced in Wails v3. Among changes, there is this one: 5dc3e21#diff-753b0daa4def34a12fc2825643a61e6d156895e753a600876d05cdf72a69f026R41 (file v3/pkg/application/dialogs_linux.go, line 41: InvokeAsync → go func())
It causes dialogs to segfault under GTK3.
To Reproduce
- Run
go run main.go in v3/examples/dialogs on Linux.
- Open any dialog.
- Click button in the dialog.
App crashes, log: https://gist.github.com/nsychev/1957f31776c267f137d541d10ce3ec40
Expected behaviour
Dialog closes.
Screenshots
No response
Attempted Fixes
AI agent said that in GTK3 dialogs must be dispatched to the main thread, so go func() is incorrect and previous version with InvokeAsync must be used.
After vendoring wails and changing this line, dialogs are working as expected.
