In Joel's repository SDL2 was finally mostly fixed in version 2.0.12. Before there was some artifacting and the video memory would run out when loading more than one image or a bigger image. There is still an issue with SDL2_ttf, but it is a big upgrade either way.
To clarify, text doesn't always draw like expected with SDL2_ttf at the moment. It can be a bit garbled. Everything else I've tested seems to work like expected, including using SDL2_image and SDL2_mixer.
