automatic resolution change after turning stopped working

[tmu-sprd]

Environment

• OS: Gentoo
• Scrcpy version: 3.1
• Installation method: from Portage
• Device model: Google Pixel 8a
• Android version: 15 (Build: BP1A.250305.019)

Describe the bug

My Google Pixel 8a got a system update this week to build number BP1A.250305.019 of Android 15. In the previous build of Android 15, turning the phone changed the screen resolution of scrcpy from landscape to portrait automatically. In this build, this stopped working.

Before the update, turning the phone printed INFO: Texture: 2400x1080 and changed the resolution.

Now it looks like this, without resolution change:

Looks like your device does not trigger a display changed event as expected: e26bdb0 39d51ff

Seems like a duplicate of #5881 and #5853, but with Android 15.

I just upgraded my Pixel 8 after reading this issue, and I can reproduce.

At least, the timing is perfect, I should have some free time this evening. I know what I'm going to do 😅

Thanks a bunch in advance.

Given the work already done for this same problem for Android 14, the fix is in fact trivial:

Replaced, tested and it works.

The provided patch also work for Pixel 7 Pro under Android 15 after Mars update.

Pixel 6 fully updated. Running Linux fedora 41 fully up to date . Updated scrcpy about an hour ago. Test just now and I'm having the same problem. Earlier today before I updated scrcpy it was working fine.

wonder if any one here can teach a man to fish? I usually wait for the fix to be done by the coders of scrcpy. I've been trying to add the patch in this thread with no luck. The problem is that that my phones battery is over heating and it has swelled to the point that it has popped the screen out lol. ordered a new battery from ifixit wont be here till Saturday the latest. so I try to keep the screen off phone calls and the hot spot for the cpu only. the battery stays cool. i figure if I can install the patch and keep the screen off I can you the phone as normal on the pc screen. Soon on the 20th I get a new amount of hot spot data so I can use the cpu when Im on the road but I would still like to learn this for future use Thanks anyone.
