Enabling scrcpy after changing the screen resolution with adb will result in a significant drop in the cast frame rate

[matou314]

• [✔️] I have read the FAQ.
• [✔️] I have searched in existing issues.

Environment

• OS: [Windows11]
• scrcpy version: [2.4]
• installation method: [e.g. manual build]
• device model: ASUS_AI2205_A
• Android version: [14]

Describe the bug
When I use adb first to change the screen resolution ("adb shell wm size 1080x1920")
launch scrcpy and the frame rate of projection on the computer will be reduced, and the latency will increase significantly
But when I start scrcpy first, and then use adb to change the screen resolution, the frame rate does not decrease. But the mouse click will be offset on the phone screen

On errors, please provide the output of the console (and adb logcat if relevant).

Here are the output logs:

1. The resolution has not been changed

When I use adb first to change the screen resolution ("adb shell wm size 1080x1920")
launch scrcpy and the frame rate of projection on the computer will be reduced, and the latency will increase significantly

I don't know why, but my hypothesis is that if the size is not the native resolution, the system probably performs an intermediate filter which reduce performances.

But when I start scrcpy first, and then use adb to change the screen resolution, the frame rate does not decrease. But the mouse click will be offset on the phone screen

Probably because the resolution change is not detected: #4469

When I use adb first to change the screen resolution ("adb shell wm size 1080x1920")当我使用adb首先改变屏幕分辨率（“adb shell wm size 1080x1920”）
launch scrcpy and the frame rate of projection on the computer will be reduced, and the latency will increase significantly

I don't know why, but my hypothesis is that if the size is not the native resolution, the system probably performs an intermediate filter which reduce performances.

So is there any way to fix the problem of frame rate dropping after changing the resolution? Thank you very much!
