Tried to set display timing properties without the correspon

Error message

Tried to set display timing properties without the corresponding feature ({:?}) enabled.

What it means

`Swapchain::set_next_present_time` schedules a present-time via VK_GOOGLE_display_timing, which requires the `Features::VULKAN_GOOGLE_DISPLAY_TIMING` feature. If the device was not created with it, this public method panics with the feature name. It exists because hal does not have access to wgpu-core's required_features record for a nicer validation error.

Solutions

Add `wgpu::Features::VULKAN_GOOGLE_DISPLAY_TIMING` to required_features when creating the device.
Check `adapter.features().contains(Features::VULKAN_GOOGLE_DISPLAY_TIMING)` first and skip present-timing scheduling if unsupported.
Only call set_next_present_time behind a runtime feature check.

Example fix

// before
swapchain.set_next_present_time(present_time);
// after
if device.features().contains(wgpu::Features::VULKAN_GOOGLE_DISPLAY_TIMING) {
    swapchain.set_next_present_time(present_time);
}

Defensive patterns

Strategy: validation

Validate before calling

if !device.features().contains(wgpu::Features::VULKAN_GOOGLE_DISPLAY_TIMING) {
    return; // skip present-timing scheduling
}
swapchain.set_next_present_time(present_time);

Prevention

Gate all display-timing calls behind a runtime feature check.
Request VULKAN_GOOGLE_DISPLAY_TIMING in required_features only after the adapter reports it.
Provide a non-timing fallback present path for unsupported drivers.

When it happens

Trigger: Calling `set_next_present_time` on a swapchain whose device was created without `wgpu::Features::VULKAN_GOOGLE_DISPLAY_TIMING`.

Common situations: Frame-pacing / display-timing code copied from a project that enabled the feature; forgetting to declare the extension-backed feature at device creation; running on a platform where the driver lacks VK_GOOGLE_display_timing.
