Github Stats

rtx-mesh-shaders's Issues

RandR headers can't be found on the Ubuntu CLI

CMake is unable to configure to project because it can't locate the RandR include headers.

Bundled version of Vulkan doesn't compile on the Ubuntu CLI

libvulkan.so appears to be incompatible and does not compile on the Github Actions CLI.
Needs to be investigated further by running it on a local machine.

ImGui vertex buffer and index buffer destruction causes validation layer errors.

Describe the bug
"Randomly" the validation layer will give the following error:

validation layer: Cannot free VkNonDispatchableHandle 0x39[] that is in use by a command buffer. The Vulkan spec states:
 All submitted commands that refer to buffer, either directly or via a VkBufferView, must have completed execution (http
s://www.khronos.org/registry/vulkan/specs/1.1-extensions/html/vkspec.html#VUID-vkDestroyBuffer-buffer-00922)

This is because the imgui implementation can destroy vertex and index buffers at runtime while they are still being used. These buffers need to be versioned somehow or allocate a massive buffer instead.
