Hello everyone,

An hour ago I was playing Dota2 on max settings, 1600x900 res. Suddenly the display shifted and I could move cursor to the right then it goes back to extreme left.

I have taken photos as many as I could here: https://imgur.com/a/N7ESC

Well, the photos taken do not show the "horizontal lines" (like those that can be seen in a deformed VHS tape) but they demonstrate the shift I experienced.

I quickly opened HWMonitor and such and AMD's Catalyist (during gaming) and temperature was 70C. Which is normal as far as I know.

I opened Device Manager and tried to disable then enable the driver but no effect.

Only way to get out of that was by a restart. When it soft-restarted, everything was back to normal.

Then I started the match again then same thing happened. Restarted, fixed again.

I did not have any new software installed nor updated the driver (no new updates for this model anyway) nor did anything with the hardware. Only significant thing is Windows 10 latest update, but I've played many times since then and nothing happened.

This is a post by me that has some useful links about my specs (and a previous problem).

What is the cause of this problem? Is it drivers? What should I do? How should I diagnose more?

Thank you for reading.
