Of new turn to the great god, maximize winform procedure, the page is not complete, as shown in figu-CodePudding

The great god, look at the normal display interface

And then click the maximize, you become like this, (normal on Windows 7, the problems on win10)

Finally cause the code, but this code can't take out, I want to use, this code can solve the problem of page switch flicker,

If you remove the code, full display window can indeed, but flashing is too serious,
The great god what's the solution? Thank you thank you
