The 2.9.7 update appears to have made automatic refresh rate switching unreliable. I have seen this issue on two separate PCs. Usually, stopping Emby Theater and restarting it after a failed refresh rate switch will get it to work the next time. It does seem that refresh rate switching works the first time after starting Emby and playing a video, but the next video played often will not switch correctly until an Emby restart.
In the attached log the last video played failed to switch refresh rates.
