I've noticed that on Pixel devices running Android 14, the background of my app is sometimes  and suddenly replaced with solid black; this happens with and without user interaction. And it will transition back to normal on it's own as well.

This does not occur on devices running Android 13 and earlier and it does not occur on non-Pixel devices. For example, a OnePlus 9 Pro running Android 13 and an emulator running Android 14 both work as expected.

The background of my is usually solid white, but also sometimes it has a bitmap graphic as the background. This issue occurs regardless of what the background is displaying. The black flash always occurs if a PopupWindow is displayed on top of my OpenGL canvas, but other interactions, like scrolling can trigger it too.

Please see the attached for an example of what it should look like and how it looks when it's showing the black screen.

IMPORTANT: The reason that I believe that this is an Android bug and not a bug in my code is that "adb shell screencap -p" ALWAYS captures the black background, regardless of what the user sees. On the other hand "adb shell screenrecord /sdcard/video.mp4" ALWAYS captures the correct background, regardless of what the users sees.

I don't know where in the rendering pipeline screencap and screenrecord attach themselves, but they are capturing different things from each other, and also one of them is always capturing something that the user isn't seeing.
