Description:
SDL leads to tearing in opengl applications if composite extension is loaded in Xorg.
This one has a long background you can check in this thread:
https://bbs.archlinux.org/viewtopic.php?id=176651

As you can see, there will be no other sdl 1.x releases, so sdl devs will wait for sdl2 to fix the issue.
Meanwhile, fedora has fixed sdl with a simple patch very similar to the one in aur:
https://aur.archlinux.org/packages/sdl-nobackingstore/

I'm asking to use the same patch fedora uses; it has no downsides as you can see in the comments wrote by the sdl devs in the part of code that needs patching.
They seems to have just forgotten the code in that state, and newer xorg releases combined with that produced the tearing effect.
This task depends upon
