Live2D Cubism Editor hangs when two child windows are present

1. Website from where to download cubism editor
https://www.live2d.com/en/download/cubism/

2. Install and run with wine

3. Close the welcome window

4. You can trigger this problem by just dragging any image (jpg, png) into the
main window

5. An import progress window will appear and another window indicating you to
import said kind of images later, this will make cubism editor become
unresponsive and get stuck, impossible to click anything, close the import
window or close the main window

there are other ways to make two child windows appear at the same time but that
is the fastest way to make the software hang under wine, the behavior is
exactly the same in any of the other cases, so is the same problem with the two
or more child windows
