Android 10 system phone showDialog pop-up rendering issue using Vulkan. #178285
Description
Steps to reproduce
1、Create a transparent showDialog dialog box and add an update button to it.
2、When the example code below is placed on a Dialog, a black block will appear at the left corner.
This problem is resolved by disabling the new engine. Only Android 10 systems have this problem.
Expected results
I don't want black patches to appear on the cut corners.
Actual results
There are black blocks around the beveled corners of the button.
