In the past, i used an older version of the driver to get rid of it. But since (for whatever reason) Windows is auto updating the drivers every few weeks (even when i turned anything off for auto updates), i gave up and deal with it. The problem occurs only in the borderless window mode. In Full Screen everything works smooth.
Shamelessly quoting myself...

I found a solution for the problem above. Disabling Freesync and enabling "Enhanced Sync" for FFXIV in the Radeon Software works like a charm. Even in Borderless Window Mode.
