@luzhigang Most probably the reason is the graphics driver. Do you see any warnings/errors in the console if you start your app?

@jsulm Thank you for your reply.
Yesterday I also doubt whether was graphics driver's problem,So I checked whether have the new driver update,but it seems the driver is the latest version.
It do not have any warnings/errors when I start my app.

Hi and welcome to devnet,

Did you check if there was any difference in the hardware between the machines where your application runs and the others ?
