Not recording anymore, tried via shortcut key and clicking the record button in radeon home.
(My desktop recording is turned on so there's nothing to limit it from recording)
2-3 days ago, I used Instant Replay keybind to record some in-game content. It worked normally as it should, then yday updated to 20.4.2 and yep, it records a video of 5 minutes (as its selected in the settings) but this video is like 8mb and only displays green screen or black screen.
I see same problem with Adrenalin 20.4.2 on RX Vega 64 Liquid.
A workaround is install Adrenalin 2019.12.1 and then update 20.4.2 Drivers using Windows Update.
The Adrenalin 2019 19.12.1 GUI/UI Radeon Overlay works fine and I can start Relive Recording using it or using hotkey.
I file an AMD Reporting Form to report it and perhaps it will get fixed in next release for those who want to use Adrenalin 2020 style GUI/UI.
