I've purchased Decker for my Mac and up until recently have downloaded a release *.tar.gz to which I run "make decker && make lilt && make docs && sudo make install" on Arch. I have the sdl2 and sdl2_image libraries. All of a sudden when I run Decker there's an audible rapid "clicking" coming out of my speakers. Perhaps it has been present this whole time but I had volume down.. I've tried removing and installing older builds to no avail.. curious if anyone is aware of this or knows a fix? I've tried searching the community here and some internet searches but no luck.. 

There is currently a github issue open discussing the same problem when building from source on Arch linux.

FYI, this issue was ultimately traced to a regression in SDL2 itself; the problem was patched there and should be corrected as of the next SDL2 release.

Awesome! Thanks for the heads up.
