Looks like you are rendering without using requestAnimationFrame for the main loop.

Hello , I try export a sdl3 project to the web, the program is running but browser report some error ,any idea about this ? I use callback-based main loop so there should not have this issue!

Usually this means you did some render API things from SDL_AppInit() before the mainloop is set up. If you can post some code, I can take a look!

i'm getting this too. i emptied my SDL_AppInit but no difference.

This popped up in another issue, too. So we're all looking in the same place, let's all move to #12805.
