Our project is based on Linux Redhat 7 and disabled the "gdm" service. and when the user tries to resize the window which is based on the X window, the program will suddenly freeze, until the user has done the resize operation. The resize can also be triggered by pressing alt+F8.
the freeze is causing the X canvas to stop refreshing and leaves a static picture on the screen.
here is the video showing the problem.
Has anyone ever encountered a similar situation? Is there any solution to this problem?
Thanks a lot.
