asus hiccup flickering - YouTube


My powercolour r9 270 is doing exactly the same thing as this video in some games. Like the screen does a jump / hiccup.

It does not do this on the desktop, regular apps or in Firefox both under windows 7 64 bit and Linux Xubuntu 14.04 LTS so I cannot see it being the cable or monitor.


Originally on 16.3 drivers and updated to 16.5.2 and both have this issue. The new 16.6.1 drivers still have this issue. Screen hiccup occurs most obviously in GameDev Tycoon which is a chrome based (ns.js / ns.exe driven) and also on the static pre scavenge screens in the game This War of Mine.


Also done a full clean install :- uninstalled fully, reboot safe mode, run ddu.exe, reboot, install new 16.6.1 drivers
