Qt UI problem

我们在项目开发过程中，发现在滑动切换不同的UI界面时，会出现拖影现象.
我们采用同样的硬件，都是RGB输出，试验了如下Qt版本：
5.4.2、5.5.1、5.10.1 未出现拖影现象
5.9.7、5.12.4 拖影现象明显

During the project development process, we found that when sliding different UI interfaces, smear phenomenon will occur.
We use the same hardware, both are RGB outputs, and tested the following Qt versions:
5.4.2, 5.5.1, 5.10.1 No smear phenomenon
5.9.7, 5.12.4 The smear phenomenon is obvious
