The logs are indicating that it is switching to 23.976Hz display modes each time. What indications do you have that this isn’t the case?
Ugh, gotta love Windows APIs. If you change the resolution/refresh rate via the APIs, then toggle HDR, it flips back to the previous resolution/refresh rate. But if HDR is flipped first and then resolution/refresh rate is switched, then it works. Maybe is MS had documented the API that they put in their headers for developers to use the docs would’ve mentioned this.
Turns out there is a public but undocumented Windows API to do it.
I informed the developers of it a few weeks ago but I get the impression that they don’t really care since it doesn’t occur in their standalone player. Only when wid is set can it occur.
