Android UI is completely black in v1.33 development builds

[w-pearson]

Description

Since ade34bb59da916d6fff1846ba1729e18248b2669, Android UI is completely black when capturing with renderdoc, though actual Vulkan rendering works fine.

Steps to reproduce

1. Build and install the Khronos Vulkan samples. (I think I have e1277f46e0ddf6b59f11268a4e977ea43630c044 installed but I'm not 100% sure.)
2. In renderdoc, launch com.khronos.vulkan_samples/com.khronos.vulkan_samples.SampleLauncherActivity without any intent arguments.
3. Observe that the sample selection screen screen is completely blank.
4. Note that tapping the screen will select a sample and those will render correctly.

I believe the relevant logcat output is this:

Note that the sample selection screen isn't presented using Vulkan - RenderDoc says "API: Vulkan (Not Presenting)" and the capture buttons are disabled. I'm not entirely sure how it works internally, beyond SampleListView using android.view.View. This might be implemented internally using ANGLE, but I'm not sure of that.

I don't expect to be able to capture the selection screen with renderdoc, but being able to see it makes it much easier to select the correct sample.

Environment

• RenderDoc version: v1.33 development builds, bisected to start at ade34bb59da916d6fff1846ba1729e18248b2669 and also tested 22ffd90382ec82d83a11eee1bcf7db5b6d5b55cf, built from source. v1.32 release builds are fine.
• Operating System: Android
• Graphics API: Vulkan

What device are you seeing this on?

[cmannett85-arm]

I've tried on:

• Vivo X90 Pro
• Google Pixel 8
• Samsung A34

All rendered the selection screen whilst background capturing. The Vivo and Samsung presented as OpenGL ES but like yours the Pixel had "API: Vulkan (Not Presenting)" and Warning - Required size changed on image between external/non-external, banning dedicated memory printed in the log, but it was still displayed.

I'm seeing this on a Samsung development device. It's possible that it's limited to development devices or the driver I have on that development device; I'll check a personal device as well.

Looks like this was an issue with the development device; I could see the selection screen properly after I updated the Vulkan and GLES drivers. It seems unlikely to me that any production devices use the affected drivers. Sorry for not trying that first!

I did test on a personal Galaxy A15, and that one presented as OpenGL ES (and also was unaffected).
