[4.14.5] [Arch Linux] xfmw4 sometimes core dumps if using fullscreen application or fullscreen browser video

Sometimes using the fullscreen mode in firefox or starting a fullscreen application (videogame) xfmw4 seems to die It restarts itself but now right click menus and some applications stay invisible until I reboot the computer.

It also happened before I started using redshift and at the moment it isn't active due to my GPS coordinates.

That's what I see in the journal

(xfwm4:78855): Gdk-ERROR **: 22:14:06.711: The program 'xfwm4' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadPixmap (invalid Pixmap parameter)'.
  (Details: serial 20874541 error_code 4 request_code 54 (core protocol) 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 GDK_SYNCHRONIZE environment
   variable to change this behavior. You can then get a meaningful
   backtrace from your debugger if you break on the gdk_x_error() function.)
