another linux issue, runtime.WindowSetPosition can't change position on my ubuntu. (but works on windows)

func (a *App) startup(ctx context.Context) {
	a.ctx = ctx
	runtime.WindowSetPosition(ctx, 100, 100)
}

Thanks for raising this. Please split into 2 issues.

The first issue, what did google give you? Did you read this? https://github.com/Ulauncher/Ulauncher/issues/667

[zhangpy]

you could take a look at the zip file to reproduce it. The project is created by wails command and I modified a little. https://github.com/wailsapp/wails/files/8862072/w.zip
