Based on your description, I recommend you to uninstall the current driver you have and install the latest for your Intel ® Graphics controller that can be downloaded at the following link:
It is also important to confirm with the system manufacturer if they may offer any download for their customize software.
Updated Mirillis Action! to the latest 1.15.2 -> no crashes but still recording may be aborted anytime and there are frame drops.
Tried to completely uninstall Intel drivers for integrated card and installed latest version (3165) -> no positive changes. Updated AMD drivers for discreet card (latest Catalyst 13.8 beta2) -> no positive changes.
Maybe I should completely wipe OS and reinstall everything again?
PS. Here is an example of video record: Bug report video - YouTube , all other videos you can watch on this youtube channel were recorded on a same computer but with older drivers.
Looks like I've found a way to fix my problem -> connect monitor to iGPU, not to dGPU. Also I downgraded drivers for discreet card to Catalyst 13.1 which allowed me to use HyperFormance and Virtual V-Sync features of LucidLogix Virtu MVP in some programs I was not able to before (Tera).
As time went by after some software updates I'm again facing weird problems with Quick Sync.
The only thing which changed in my PC spec since the first post here:
My GPU: Radeon HD 7770 -> Radeon HD 7850
My current drivers are the latest
AMD Catalyst 14.11.2 Beta
Intel 126.96.36.199.3958 (153330)
Windows has all the latest updates from Microsoft.
Mirillis Action 1.18 and 1.19.2
Sometimes (quite often actually) Mirillis Action (both versions) crashes. Happens only when I record with Quick Sync encoder enabled. Connecting monitor to another ghaphics card does not help.
