Before you install

• Windows: this release is not code-signed yet. SmartScreen asks before it runs: More info › Run anyway. Where Smart App Control is on, Windows refuses unsigned programs; see the code signing policy.
• Android: no automated check has started this APK: CI's emulators run x86_64 and it is built for arm64. If it does not open on your phone, say so.
• Phones without Vulkan: the OpenGL ES path is new and has only run on an emulator, not on a real phone.
• Blurred backgrounds on Windows: tested on Windows' software renderer only, not yet on a real graphics card.
