Framerate drops after a few seconds

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

Environment

• OS: [Windows 10]
• scrcpy version: [latest]
• installation method: [Windows prebuilt archive]
• device model: Xiaomi Mi10T Pro
• Android version: [Android 11 MIUI Global Stable 12.5.10]

The framerate drops to ~5fps after a few seconds or a few minutes after starting scrcpy. It was not happening before. I tried to reinstalled scrcpy and sndcpy because i first thought sncpy could be the issue, it did nothing, i had to hard reset my phone (because the developper options turned it into a brick after trying some things) and it changed nothing too. I still have the issue and i've tried everything I could and I have not find how to fix it. It may be coming from my pc but I have no idea what it can be.

If you record:

scrcpy --record file.mp4

Is the recorded file also at 5fps?

If yes, it's the device.

I find out it was streamlabs that was making scrcpy lagging while trying to record the mirroring, i deleted the window capture source and the framerate stopped lagging. Its still working fine now even if i add scrcpy again in streamlabs. I don't know what happened.
