Wow.. several days and not even a suggestion... Come on guys this is affecting my work.
Check Event Viewer and note any issues with the driver in there.
If it's crashing (causing the screen to blink in and out) that may be a driver bug that needs to be reported.
Might also be worth checking with your manufacturer, see if they released any firmware updates to improve that behavior.
Ok thanks for the hint, I've never had to look in there before.
This is what one of the crashes due to driver failure reported:
Log Name: System
Date: 11/08/2015 01:04:18
Event ID: 4101
Task Category: None
Display driver amdkmdap stopped responding and has successfully recovered.
<Provider Name="Display" />
<TimeCreated SystemTime="2015-08-11T00:04:18.000000000Z" />
OK, definitely the driver you are using right now.
If you have any of the older Catalyst packages for 7/8.1 they should work with Windows 10 (but haven't been tested thoroughly for compatibility)
I would try giving one of those a shot and see if they do the trick.
