Description
- BindlessSceneViewer
- Crashes with error below when GPU draw call generation is unchecked, even when gpu is not really out of memory
[mvk-error] VK_ERROR_OUT_OF_DEVICE_MEMORY: Lost VkDevice after MTLCommandBuffer "vkQueueSubmit MTLCommandBuffer on Queue 0-0" execution failed (code 3): Caused GPU Address Fault Error (0000000b:kIOGPUCommandBufferCallbackErrorPageFault)
ERROR (SwapChainVK.hpp:356) - VK::Apple M2 Max - AcquireNextTexture(): vkAcquireNextImageKHR returned -4
- Readback
- Half of the tooltip is not showing, was fine before (MoltenVK related?)
- Wrapper
MoltenVK did not release a new version yet so Vulkan SDK still does not have an implementation for vkGetDeviceBufferMemoryRequirements. Also if we can determine a fixed location for libvulkan.dylib on macOS that would be better instead of manually pointing to VulkanSDK path, maybe we can use VulkanSDK env vars?

Research direction
Start by reproducing the three reported cases on macOS: BindlessSceneViewer's GPU draw call crash, Readback's truncated tooltip, and Wrapper's MoltenVK/Vulkan SDK behavior. Inspect the corresponding example entry points and compare the failures with the reported MoltenVK and Vulkan SDK constraints; done means each reported issue has a confirmed resolution or documented limitation.
