Hi!
I downloaded the .6136 driver (GPU Driver version 24.20.100.6136 and date 24/05/2018) and the even newer .6194 that intel uploaded yesterday (GPU Driver version 24.20.100.6194 date: 20/06/2018)... although both have the same Intel Display Audio version 10.25.0.8 and date 7/5/2018.
I tested both versions and i didn't see any difference, except in the logs are not appearing anymore the message "WASAPI OnSessionDisconnected 00000000" ?!?!?!
The only minimal difference that i saw, it was with the .6136 driver and when i set native and 50 Hz refresh, with this configuration during a second i could see the amiga emulator screen, although it was paused and soon after that, WinUAE closed and left me in the desktop.
Sorry, it looks that is a 1000% intel driver problem
