scrcpy fixes my phone's refresh rate to 60

[zh0ngtian]

Environment

• OS: macOS 12.6
• scrcpy version: 2.0
• installation method: brew
• device model: samsung z fold4
• Android version: 12

Describe the bug When I launch scrcpy and then close it, my my phone's refresh rate is fixed to 60, and only reboot can bring it back to 120.

Weird.

It should not have any impact, but could you test with this change?

How do you observe that it is 60 or 120 in practice?

[zh0ngtian]

I open the "Show refresh rate" in "Developer options".

[zh0ngtian]

Now the refresh rate is fixed to 120, the refresh rate should be "adaptive".

I've also noticed this recently and +1 that a reboot of the device "fixes it". Other things to note is that the refresh rate of the device appears capped even disconnected from scrcpy (via disconnecting USB).

Weirdly enough, enabling 'Show refresh rate' option shows the device at 120 and scrolling appears smoothly again. Turning off the option, appears to lower the refresh rate back what I assume is 60.

Same issue here on the same device model (Galaxy Z Fold 4). I also have my phone refresh rate at adaptive normally
