After the scrcpy window poped up, I clicked another program window and used another program.
When I clicked back to the scrcpy window, the system was stuck, the cursor couldn't move. Then the system crashed and rebooted.

There was no chance to see the terminal output when system crashed, but after rebooting, the system had a crash report.

panic(cpu 2 caller 0xfffffe002a62ce5c): DCP0 PANIC - program_swap: Async Swap request landing on unsupported platform. Force panic
 - iomfb_driver(11)
program_swap: Async Swap request landing on unsupported platform. Force panic

I found a relative issue.

Seems that it is Sonoma 14.4 issue. I had the same reports and kernel panics 5-6 times a day. Formatted my SSD and installed 14.3.1 from the USB - works like a charm.

sure enough I shouldn't have upgraded the system 🤕

I can confirm this. Kept getting DCP panic about every two hours. Stopped using scrcpy and have been running without crashes for ~24 hours now.

I have the same issue in my Mac and Sonoma system. The solution is to run Scrcpy in Parallel Desktop, and DCP Panic doesn't show anymore.

[digvattul]

I am still encountering this issue after updating to Sonoma 14.4.1.

[kikogassen]

Same issue here on Sonoma 14.4.1

[rajohns08]

Yeah still seeing this in 14.4.1 as well

I recommend using the AS Device Mirroring as a temporary solution until the problem is fixed (it's been reliable for me).

[digvattul]

Have been using scrcpy again for a few weeks after updating to macOS 15.1 (Sequoia). No crashes so far.
