  • Reed–Solomon Error Correction

Permissions

2 permissions weaken the sandbox. Flatsonar asks before installing.

  • full access to your entire file system
    --filesystem=host
  • X11 display: X11 lets apps read input and windows of other apps
    --socket=x11
  • inter-process communication (needed for X11)
    --share=ipc
