Black screen Vulkan Android Pie

Hello, I know if have some thread about this topic, but I want just know, Why Android Pie with Vulkan 1.1.66 get black screen on every game ? I have PocoPhone F1 with stable miui 10 (Pie), I test other custom rom's, but none get vulkan works on dolphin. PPSSPP works very well ( I Know PPSSPP have different build and builder), but I need know where is the error Android 9 made for dolphin ?

From user JonnyH "The latest qcomm drivers have problems with vulkan. It should be fine using OpenGL. And certainly in my testing, the vulkan backend was a small improvement over the OpenGL, but not massive. While annoying that Qualcomm have broken their vulkan driver, it wasn't enough for me to suddenly make unplayable games great over OpenGL."

Also, PPSSPP is a less driver intensive app.

"driver intensive" is a bit of a weird phrase, but I guess from the perspective of the user it's close enough.

PPSSPP does not need to emulate the batshit insane things the Wii's CPU and GPU can do to render a frame. So it can get away with using some more common techniques which are better tested in most drivers.

Additionally, PPSSPP just has graphics developers that care very much about Android and will work around bugs whenever they can. Dolphin, not so much.

I roll back for Oreo version,l compiler the latest vulkan are avaible from Qualcomm (1.1.66), on Android Pie it broke texture render, on Oreo it rendering normal without problems. I was thinking about Dolphin need small patch or hack to see what Android 9 give little conflict with Dolphin on vulkan.
