Vulkan renderer results in graphic glitches #134

Open markusbkk opened 4 days ago

markusbkk commented 4 days ago

I'm currently in the process of assessing graphics middleware solutions for my own little game engine (the choice is now pretty much down to LLGL and DiligentEngine).

LLGL works great for OpenGL but as soon as I switch to the Vulkan renderer, I get nothing but graphical glitches in any of the included examples.

Vulkan works fine under Diligent so I guess driver issues can be ruled out? While Diligent appears to have shipped with its own copy of the Vulkan SDK, I had to run sudo apt-get install libvulkan-dev for LLGL. Do I need a different version of the SDK, maybe?

OS: Pop! OS 22.04 GPU: Radeon 760m (iGPU)

EDIT: Vulkan SDK is version 1.3.280.0

Hi, I just got back from a business trip and got sick on the way back. So I can only sporadically respond here. In the meantime, can you try launching the example with -d to enable debug mode, including the Vulkan validation layers? That should provide some insight what's going wrong. Have you also tried running the example through RenderDoc?

No worries. My own father recently burglarized my home so I'm not super focused on software development myself right now.

Will debug it tomorrow.

Get well soon.
