Mouse going out of the window game screen

Does everyone have the same problem like me?
My laptop is low-end, so I play WT with Window mode, it’s OK at the first time. But from the Sky Guardians update, my mouse has gone out of the Window game screen, especially when I used air vehicles or drones. So is there anyway to fix it?

Thanks.

Can you share some screen shots?
also can you share your specs?
