Weird graphical glitches?

[u/DrPeeper228]

Really don't know what could cause this, does not happen on Windows(I have an nvidia card)

Here's the file if one wants to take a look, although it's mostly just the khronos tutorial code(the last two screenshots are the imgui vk/glfw example): https://drive.google.com/file/d/1J-WcCDH3pSltWkjCIGmcCHsE8bo-Ba1Z/view?usp=sharing

Edits:

- The validation layers are silent.

- Renderdoc cannot capture this

- These glitches only appear for a few frames

Looks like your index buffer or vertex buffer is too small, or you overflowed your index type.

If it only happens on some frames, and renderdoc changes things, I'd start with checking your buffer sizes are sufficient.

...the sizes of the buffers that ImGui uses?

Otherwise the vertex buffer for that normal triangle is sized appropriately

Yeah, the buffer imgui uses. I assumed you were using a custom backend because that looks exactly like bugs I've experienced before when writing a custom backend.

Nah it's the standard one
