…OR_OUT_OF_DATE_KHR. This may happen when resizing and the surface size is changed after calling AcquireNextImageKHR and before calling vkQueuePresentKHR.

When the Avalonia app with Vulkan backend is resized, a VK_ERROR_OUT_OF_DATE_KHR exception may be thrown after the call to
vkQueuePresentKHR(inVulkanDisplay.cs).This may happen when the user is resizing the window and the surface size is changed after calling AcquireNextImageKHR and before calling vkQueuePresentKHR.
The exception is handled in the try...catch block in
ServerCompositor.RenderCoremethod and as far as I know it does not cause any harm to the app. Anyway, the exception prevents callingVisualReadbackUpdatePassandExecuteServerJobs(_receivedPostTargetJobQueue)in theRenderCore. But I do not know how important that is.What does the pull request do?
The pull request handles the
VK_ERROR_OUT_OF_DATE_KHR,VK_SUBOPTIMAL_KHRandVK_ERROR_SURFACE_LOST_KHRresults that are expected when callingvkQueuePresentKHR. This is handled in the same way as after callingAcquireNextImageKHR(inStartPresentationmethod).
