Hi
We have managed to somewhat replicate this now. It is caused by a combination of GPU, Monitor features (VRR / Freesync), and control panel settings in AMD Adrenaline.
We had some success in restoring it to the way it previously worked by changing Freesync / VRR-related settings in the AMD control panel. I’d recommend taking a look at the settings and try toggling them off and see if that helps.
We’ll be visiting this issue in the future, but there is something funky (technical term) going on here. It only impacts very specific setups, so we’ll be speaking with our partners to try and narrow down the exact reason.
