System information

Samsung Galaxy J5 2016 - Snapdragon 410 - Adreno 306 - Android 7

Issue description

Rendering output is just flipped vertically. Can't reproduce on Vulkan since it is not supported on tested device. On Android 8+ (Samsung Galaxy J7 2016 for example) this is not reproducible.

With force MSAA x4 enabled, screen is just flickering on splash screen on 4.5-dev4 and lower.

Steps to reproduce

Run any project on Android 7.

With force MSAA x4 enabled, screen is just flickering on splash screen.

Is this on all versions?

[Summersay415]

No, only on Android 7, on Android 8+ everything is fine

Sorry, I meant Godot versions. Can you still reproduce the screen flickering in 4.5 Beta 3?

I’ve been testing regularly on Android 7 over the past few weeks but haven’t encountered this issue. That said, I was testing on an emulator, not a physical device.

The PR in question touches code that implements a workaround for snapdragon 400 devices that involves flipping the screen. So you likely need to be on a physical snapdragon 4xx device to reproduce

No, it's gone
