 #### I get errors like "Option not found" after merging one of these branches
 The changes to `default_config.json` or similar files weren't detected by meson due to missing regen dependencies. You can either merge the `bugfixes` branch or rebuild from scratch.
 
+#### The video is desynced / Frames don't appear at the right time
+This is probably due to the ffms2 seeking bug ([#394](https://github.com/FFMS/ffms2/issues/394)). On Windows, this shouldn't happen anymore. On Linux, you need to install the latest git version of ffms2 - for example the [`ffms2-git`](https://aur.archlinux.org/packages/ffms2-git) AUR package on Arch linux, or just compile it yourself.
