Thanks for confirming Guys
V6 should less flicker than V7 so it would be my preference but i was not sure that V6 will works for you
So after analysing logs and V6 works for you both, i will go with this one and commit the change to a new madVR Build
@Chisum can you make a new logs based on next madVR Build ? (or with V6) but can you enable log level to debug ? (there is a bug in watchdog and debug level didn't change to debug, we need to fix that for sure, so your logs hasn't debug log line to compare with @RobNorthcott
Thanks.
Here Logs V6 with debug level. This time with short flickering before start of the every video with refresh rate change, last try with v6 above was better.
