Wails app crash when Frameless attribute is use in two apps in a row on Linux

[daciot]

Description

Warning: This is an intermittent bug that sometimes works well and sometimes does not.

The application only crashes on Linux when I create two applications in a row (the second one only starts after the first one is closed). I've noticed that this behavior occurs when I configure the attributes. Frameless and Linux like the code below

func main() {
        
        app := NewApp()
    
        err := wails.Run(&options.App{
	        Title:     "First Window",
	        Frameless: true,
	        OnDomReady: func(ctx context.Context) {
		        runtime.Quit(ctx)
	        },
	        AssetServer: &assetserver.Options{
		        Assets: assets,
	        },
	        BackgroundColour: &options.RGBA{R: 27, G: 38, B: 54, A: 1},
	        Bind: []interface{}{
		        app,
	        },
	        Linux: &linux.Options{
		        WebviewGpuPolicy: linux.WebviewGpuPolicyNever,
	        },
        })
    
        if err != nil {
	        println("Error:", err.Error())
        }
    
        err = wails.Run(&options.App{
    
	        Title:     "2nd Window",
	        Frameless: false,
	        AssetServer: &assetserver.Options{
		        Assets: assets,
	        },
	        BackgroundColour: &options.RGBA{R: 27, G: 38, B: 54, A: 1},
	        Bind: []interface{}{
		        app,
	        },
	        Linux: &linux.Options{
		        WebviewGpuPolicy: linux.WebviewGpuPolicyNever,
	        },
        })
    
        if err != nil {
	        println("Error:", err.Error())
        }
     }

To Reproduce

1. Create a simple wails app using the command "wails init -n myproject -t react"

2. Replace the function main inside main.go for the follow code

    func main() {
        
        app := NewApp()
    
        err := wails.Run(&options.App{
            Title:     "First Window",
            Frameless: true,
            OnDomReady: func(ctx context.Context) {
    	        runtime.Quit(ctx)
            },
            AssetServer: &assetserver.Options{
    	        Assets: assets,
            },
            BackgroundColour: &options.RGBA{R: 27, G: 38, B: 54, A: 1},
            Bind: []interface{}{
    	        app,
            },
            Linux: &linux.Options{
    	        WebviewGpuPolicy: linux.WebviewGpuPolicyNever,
            },
        })
    
        if err != nil {
            println("Error:", err.Error())
        }
    
        err = wails.Run(&options.App{
    
            Title:     "2nd Window",
            Frameless: false,
            AssetServer: &assetserver.Options{
    	        Assets: assets,
            },
            BackgroundColour: &options.RGBA{R: 27, G: 38, B: 54, A: 1},
            Bind: []interface{}{
    	        app,
            },
            Linux: &linux.Options{
    	        WebviewGpuPolicy: linux.WebviewGpuPolicyNever,
            },
        })
    
        if err != nil {
            println("Error:", err.Error())
        }
     }
   

3. Run wails build

4. Run the file created in step 3 from the 'myproject/build/bin' directory

5. If the problem does not occur, repeat step 4 (the bug is intermittent)

Expected behaviour

The application should open without any errors.

Hi there 👍 We don't support calling Run() multiple times or multiple windows this way, however it's coming in v3 which you're welcome to test: https://v3alpha.wails.io
