## Description Using shader specialization constants to size global arrays doesn't work on the Mac. We have a need in our vertex shader to size both a vertex attribute array...

The same semaphore is used for consecutive frames by RecordAndSubmitTask

12

`vsg::RecordAndSubmitTask` doesn't have separate semaphores per frame/swapchain image like `vsg::Window` does for image acquisition, so every frame's queued submissions signal the same semaphore, and every frame's presentation waits for the...

Avoid reusing semaphores that may still be in flight

1

Fixes validation error `VUID-vkQueueSubmit-pSignalSemaphores-00067` At the moment, this is a little bit too enthusiastic when multiple windows are affected by the same RecordAndSubmitTask. It would be sufficient to use any...

Crash on record with nested views.

11

Commit 32262f8 which resets the state stack during record when it visits a View made the assumption that views were not nested. In our use-cases, we make extensive use of...

Potential performance issues raised by Best Practice and Performance validation layers

To try and discover why `vkBeginCommandBuffer` is taking much longer than I consider reasonable, I ran vsgviewer with some of the optional extra validation layers active. Here are some of...

Errors for a Clear Attachment for Stencil values if first in a vsg::View

I have a stencil clear attachment that I initialize like so: **VkClearValue clearStencilValue{}; clearStencilValue.depthStencil = { 0.0f, 0 }; VkClearAttachment stencil_attachment{ VK_IMAGE_ASPECT_STENCIL_BIT, 1, clearStencilValue }; VkClearRect rect{ m_camera->getRenderArea(), 0, 1...

Avoid creating staging buffers in TransferTask that exceed the Vulkan physical device property limit

10

# Pull Request Template ## Description TransferTask::_transferData() can create a single staging buffer who's allocation size exceeds the Vulkan physical device maxMemoryAllocationSize property limit. Windows NVidia drivers tend to be...

use rendergraph renderArea as scissor instead of viewport

4

In our application we frequently have views which are partially outside of the window's render area. In this case, the viewport is used to determine aspect ratio and should be...

Failed to render HeightMap

**Code: { vsg::ref_ptr settings; settings->elevationLayer = "http://127.0.0.1:80/wdem/{z}/{x}/{y}.tiff"; settings->elevationScale *= 100.0; settings->elevationLayerCallback = [](vsg::ref_ptr data)->vsg::ref_ptr { if (data.get()) { data->dirty(); } return data; }; } We guess the displacementMap is not...
