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

[shujaatak]

I made no changes to the source code and I get the result shown in the below screenshot. I noticed that I can drag the window by holding mouse on the black bar, the buttons events occur in the black location where the buttons should be located however the icons are displaced below it.

i use Qt5.12.4 msvc 2017, Win10 1903, no this question.

[barry-ran]

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

it's not good , i use Qt5.13.1 msvc 2017, Win10 1903, i have the same 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?

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

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
