SDL3 no supported SDL_GPU backend found (renderdoc)

SDL Development

I’m working on an SDL3 GPU app which works fine when launched directly. However, when I need to debug some of the graphics and attempt to launch via renderdoc the error received from SDL is:

No supported SDL_GPU backend found!

I’ve searched a few places which mention that if using wayland that renderdoc may be having issues. I’m not bringing this up as an SDL issue but I figure in this community someone has already been down this road and knows how to get this combination of items working?

Wayland + SDL3 + renderdoc

I’m running on arch with SDL3 (v3.4.8) and renderdoc (v1.43).

Thanks

I just stumbled onto something which worked for me. When launching qrenderdoc, if I set the env var WAYLAND_DISPLAY=”” (empty string) then it works. Although the window is quite small probably having something to do with high dpi.

$ WAYLAND_DISPLAY="" qrenderdoc
