Going to be real honest here. Thanks to the recent news related to pirates flatpaking wine games, I was able to modify their creation script and use it to flatpak league of legends. I’ve uploaded everything to github to hopefully serve as an example to anyone else interested in the process. I’ve also made the script pull all code from ubuntu web sources and compile it using flatpak build, so no precompiled libraries are used or pulled from the host system during package creation. WARNING: This thing compiles wine, and will take a while.

DISCLAIMER:
It has some fps issues on my vega 64 due to the mesa version that comes with flatpak (17.2.2), however on nvidia its working fine. I could use some input from RX 500 and lower series users on performance, as well as intel.

Tested on:
r5 1600 + Nvidia GTX 1050 (~55-70fps)
r5 1700x + AMD RX Vega 64 (~30fps) – possibly do to flatpak mesa version. Natively it runs 120-180fps
