Attempted to fix by starting FFXIV in Windows 7 Compatibility Mode. No luck, problem still persisted. Also attempted updating my drivers (turns out they were actually out of date), and that didn't fix it either. Also tried uninstalling my controller's drivers and re-installing them. That also didn't work. So short of downgrading my entire OS to Windows 7 (incredibly tedious, incredibly expensive procedure) and praying to the technology gods for a fix to be found to this issue, I am officially lost.

Also, this issue has been occurring since launch and has remained unchanged through every single patch and update to FFXIV.
