I've been trying to use both SDL2's Canvas and egui_sdl2_gl at the same time, but unfortunately it seems like they mix quite badly. The example code is here.

Found the answer: the problem was that SDL's Canvas is caching opengl calls until you call present(), which was preventing egui calls to be in the same frame. Calling SDL_RenderFlush fixed it. Opened a PR to rust-SDL2: https://github.com/Rust-SDL2/rust-sdl2/pull/1153
