VkResult is VK_SUBOPTIMAL_KHR in Android causing SwapChain to be recreated every frame

[HakimHauston]

swapChain.queuePresent in VulkanExampleBase::submitFrame returns VK_SUBOPTIMAL_KHR in Android.

This causes windowResize() to be called every frame, re-creating the entire swapChain.

What is the cause of this error? And is there a way to prevent this?

Any input is highly appreciated...

What device does this happen on? I can't replicate this on my Pixel 4a, but I could test with other devices.

And does this happen all the time, or only under certain conditions?

Hi @SaschaWillems

Thanks for the fast reply and willingness to take a look... I am facing the errors on all the devices I've tested with:

• Pixel 6 Pro (Mali-G78 MP20) - Android 14
• Pixel 9 Pro Fold (Mali-G715 MC7) - Android 15 Beta
• OnePlus Open (Adreno 740) - Android 13
• Vivo x90 Pro (Immortalis-G715 MC11) - Android 14

Upon hearing your positive result on Pixel 4a, I grabbed a device and run it but get the same error, this is the screenshot

The error happened all the time, starting from the first frame, I have just sync-ed to the latest commit 1615f95 but this issue also exist in my previous base as early as July (8b4ee59)
