What is the issue?

Waydroid is not able to launch a UI, and it looks like there's an invisible window in front of whatever was open before launching Waydroid.

System info

The system is Arch Linux ARM running on PinePhone Pro (can be found here).

OpenGL version string: 3.1 Mesa 22.0.0-devel (git-e4c582ee)

Linux danctnix 5.16.2-2-danctnix #1 (closed) SMP PREEMPT Mon Jan 24 14:53:13 UTC 2022 aarch64 GNU/Linux

Versions tried

• danctnix/mesa-git 22.0.0_devel.148909.e4c582ee-1 (logs will be from this one)
• extra/mesa 21.3.4-1

Reproducing the issue

On a PinePhone Pro, with Waydroid installed, start a Waydroid session:

waydroid session start

And then launch an app, for example F-Droid:

waydroid app launch org.fdroid.fdroid

This will cause the following error messages:
