Hexa.NET.ImGui Version

2.2.10-prerelease

Bug Description

Just copied the SDL3 example and it initially worked fine, but after that I've been getting Assertion failure at SDL_SetGPUSwapchainParameters_REAL (SDL_gpu.c:3221), triggered 2 times: '!"Invalid swapchain composition enum!"' error popping up. Funnily enough, pressing the ignore seems to work fine? This happens when you try to move windows out of the main macOS window, but again, ignoring it seems to work fine.

Steps to Reproduce

1. Use the example https://github.com/HexaEngine/Hexa.NET.ImGui/blob/main/Examples/ExampleSDL3GPU/Program.cs
2. Run it
3. Move an ImGui window out of the main window on macOS

Expected Behavior

Run normally

Code Sample

Platform

macOS

.NET Version

Hi, I don't know what the specific issue is but that wouldn't be on this repo, i just provide the wrapper... but you can disable those asserts via ImGuiIO DebugEnableAsserts (the exact name can vary)

And btw i can't debug for macOS, i don't own a machine with it.

Yeah I just ended up disabling viewports but thanks for pointing out DebugEnableAsserts, I'll look into that. Yeah I guess it's an SDL3 issue so closing.
