i run the go with new cef version and receive the error . how can i fix it

RunMessageLoop

The program 'test' received an X Window System error.

This probably reflects a bug in the program.

The error was 'BadWindow (invalid Window parameter)'.

(Details: serial 96 error_code 3 request_code 1 minor_code 0)

(Note to programmers: normally, X errors are reported asynchronously;

that is, you will receive the error a while after causing it.

To debug your program, run it with the --sync command line

option to change this behavior. You can then get a meaningful

backtrace from your debugger if you break on the gdk_x_error() function.)

X error handlers need to be installed, see upstream cefclient example:

What have you tried already? Did you google the error message from logs? Try disabling gpu process.

I meant GPU hardware acceleration. Use --disable-gpu and --disable-gpu-compositing flags.

hi Czarek

thank you again.

if i remove this line FillWindowInfo(windowInfo, hwnd) from CreateBrowser function

then it work .it will open the cef window .but no in gtk window .

the FillWindowInfo function i change it to :

func FillWindowInfo(windowInfo *C.cef_window_info_t, hwnd unsafe.Pointer) {

fmt.Println("FillWindowInfo")

C.FillWindow(windowInfo, hwnd)

//windowInfo.parent_window = (C.cef_window_handle_t)(hwnd)

}

and the C　FillWindow function

static inline void FillWindow(cef_window_info_t *info ,void * hwnd){ info->parent_window=(cef_window_handle_t)hwnd;}

is that something wrong. sorry ,i dont good at c and c++
