Tearing while watching embedded video in Linux

I am experiencing an annoying horizontal screen tearing while watching embedded videos in Firefox 49 on Linux Mint 17.3 KDE 64bit. The issue is only present in embedded view, switching to full screen view stops this behaviour almost every time. It happens both with HTML5 video and flash video. Any suggestions?

In case anyone should mind, I got this issue solved by enabling vsync in desktop settings :)

Disabling hardware acceleration did not solve the issue. Enabling xrender does not solve the issue either but this reduces turds in text fields. Here's the support info:
