Facing issues on Windows 10, Qt 5.12.1 MSVC 2015 & MSVC 2017 about framelesshelper

[lvzhaobing]

在main 函数设置如下属性：
QApplication::setAttribute(Qt::AA_UseOpenGLES);
可以临时解决这个OpenGL 渲染错位的问题，应该是比 Intel(R) HD Graphics 5000 更早的集成显卡会出现黑色边框。
运行环境：Qt5.14.1 + VS2019 + Windows10 1909 +Intel(R) HD Graphics 4600

good, Qt5.12.2 ,msvc 2017, Win10is also perfect.
QT should have solved this problem

sorry, i can't fix this, it's caused by windows opengl driver. it has compatibility problem with windows WS_THICKFRAME flag. it happened in Windows 7. it's first time i heard in Windows 10. it's not about me, or Qt, it's problem of Windows.

I've tested that the same computer, the same environment, just changing the QT version will solve the problem, so will it not be the problem of OpenGL?

it's not good in 5.13.x? Which one is correct, 5.12.x or 5.13.x?

win10, vs2017, Qt5.12.1 is not good, Qt5.12.2 is correct

win10, vs2017, Qt5.12.1 is not good, Qt5.12.2 is correct

it looks like i have to test every single version in every operating system... orz... orz... orz...
